A few clarifications / updates: You can actually use Arm + RISC-V-just, one of each core for a frankenmonster microcontroller. Can't use all four at the same time. MicroPython has released two preview UF2s, one for the Arm cores, and one for the RISC-V cores. As many have pointed out (thanks!) RP2040 was QFN-56, RP2350A QFN-60, so the pinout is slightly different (so not an exact drop-in replacement). I don't know about ADC quality improvements or some of the other details many have asked about, so please check in on the Pi forums and in other reviews for more data-this video is meant to be a quick overview to introduce the things that mattered to me in my beginner-level use of microcontrollers :)
@@JeffGeerling an important new feature given the popularity of the RP2040 in retro integrations is 5V tolerant GPIOs, albeit the chip does have to be powered up first.
@@chris-tal Even more interesting would be cores supporting multiple ISAs with microcode or within the instructions decoder(s) of the core(s) themselves without any Frankenmonster 'gluing' together multiple cores with some sort of 'IPC'.
I do think it's important to mention that the Hazard3 RISC-V cores in this thing are actually designed by Luke Wren, to quote Raspberry Pi "currently a Principal Engineer in the Raspberry Pi chip team". They didn't just grab some open-source RISC-V CPU; arguably, they did the opposite.
Good point-I've never met Luke, but it does look like he's been on Raspberry Pi's silicon design team for quite some time! I'm guessing he was also involved in RP1/RP2040 a bit, interesting seeing how much / how long Raspberry Pi's invested in their design process.
@@JeffGeerlingi was wondering now that the pico 2 is using cortex M33 architecture, which is ARMv8, or 64 bit. However what are those 2 RISC V cores? Are they 32 bit, or 64 bit. I tried to find some information on those two Harvard 3 Risc-v cores, but I couldn't find out enough information about the RISC V cores that are inside the rp2350
I want to point out that that Lego brick *does* actually contain an RP2040 and an OLED display. The cable coming out of the back is just the USB tether to supply power. It's an incredibly impressive project.
@@petertrypsteen Indeed! Though there's no room for I/O, so all it can really do is play animations. One neat feature is that it can be powered by the same bricks as Lego motors.
Wait… has the USB port, and RP2040 can configure that for host mode. Maybe it actually could play games? Edit: Oh yeah, there is a capacitive touch sensor, so you could also play something like Flappy Bird.
@@JeffGeerling , I have a short showing of some results for my Raspberry Pi Pico raytracer. I never expected this little board to perform like that. More memory will allow me a better resolution and caches.
So I saw this Seagate project that used 2 Risc-V chips one for encryption and the other for a computer module. Also I bought a Seagate and miss my mybook I wanted to partition the drive after it was formatted to Max since I don't have a Mac anymore and I spent 2 hours with customer service for them to say do these 6 steps I said that was the first screenshot I was already on step 5 before I bothered you.
ngl the Picoboy you mentioned in the video looks pretty sick! It's a really good price for a DIY console, especially with the discount code you provided in the description! 100% getting one! Thanks Jeff!!!
The Arduboy is the same project, just much older with more support. An Arduino is the same thing as a Pico, it just doesn't have the "Raspberry Pi" buzzword.
I actually had no intention of buying one until this video. I have so many rp2040 boards. pico, pico_w, stamp, tiny2040, feather, pico-ice(rp2040 + fpga).... and then Jeff mentioned that it finally has a solid low power mode, and I have a wearable project that I originally wanted to use the rp2040 for but had to scrap because of the high power draw. Welp, if I'm going to order 1, I guess I'll order 2 for the pile.(although I'll probably order a stamp or a feather instead of the pico)
@@JeffGeerling I hate only having one of a component, especially MCUs and sensors. If you build it into a project then it is very useful to have a second just for quick tests and a spare in case something breaks. I will probably get a few third party boards even though I don’t like the rpxxxx platform and especially how you program it in C.
@@JayrosModShopI assume they designed themselves into a corner by having it on the original, and not wanting to break compatibility with the original footprint
I remember this being asked when the Pico released - Micro USB's ubiquity and companies pretty much throwing the connectors away are why the Pico uses the connector still, Type C isn't that much more expensive in price but they aren't as abundant and Pi's factory definitely have a ton left over from the past decade.
I did a raytracer for the Raspberry Pi Pico 1, and I was already impressed with the performance. I can't wait to test the same software with RPI Pico 2. I can't wait for that new amount of memory!
Looking at Arm's Cortex-M33 programming manual, I'm not seeing any instructions for double precision other than the fact that the FPU can load and store 64-bit values into two 32-bit registers. In particular, no double-precision arithmetic. Having an FPU at all is still quite a big improvement, though!
Not only that but the Pico2/M33 uses Thumb2 which a massive step up for assembly programmers. Pico1/M0+ uses Thumb1 and is incredibly difficult to 'get right' because of the severely limited instruction set. I could go in to specifics, but Thumb1 has been a major pita. Everyone who's touched the M0+ at the instruction level will be grateful for this significant change.
RPI website claims hardware divide, single precision floating point hardware, and DSP acceleration are implemented as part of the ARM M33 core. For some apps (such as FFTs) that I commonly use, those features mean more than the small clock frequency bump. Also, one more ADC channel. Will be interested in how those pan out in real world tests.
The home labbing community is the best. Your channel and the ones you're mentioning here and others you've highlighted in your other videos have created such a healthy, friendly, supportive and creative echo system. Well done, all of you.
These are the kind of risc-v cores I've been waiting for: not just open standard, but fully open source and implemented by a company with excellent support and community engagement! Great work, Raspberry Pi!
While the RP2350 is the same size as the RP2040 is not a drop-in replacement. RP2350A uses a QFN60 package whereas the RP2040 uses a QFN56, meaning 4 more pins, plus the pinout is a little different.
Jeff, I love your content. I also love that you point out that you're a beginner at some of this, as well as point to other creators! It shows us that you're really in it to **HELP** the community. We appreciate that. Keep up the good work, sir! ❤
Thanks! The only way to learn is to try new things, fail, try again, fail, etc. Hopefully sometimes you succeed but sometimes you just realize something isn't really in your wheelhouse... for me, at least for now, that's low-level programming :D I stick with micropython, which can do most of what I've ever needed to do with a microcontroller!
"The guy with the Swiss accent"... not to mention his tiny pointing hand... I can't think about him without thinking about that tiny pointing hand! 😂 I'm looking forward to seeing more about that B version, if anything to see what the additional GPIO provides. And of course, because I'm currently working on a project with the Pico W, I can't wait for the W version of the 2 to release as well.
That's a really good idea to include the RISC-V cores *in addition* to familiar ARM cores. That's a beautiful way to lubricate the transition into a new world. No USB C, though. I wonder why? It is physically larger which is the only reason I can produce to stick with micro USB.
USB-C isn't better than Micro-USB. Micro-USB is cheaper. Micro-USB is easier to solder too. If you want USB-C, there are tons of ESP32/Arduino boards out there with USB-C. They are the same thing as a Pico.
Back when Pi Pico was introduced, nearly 4 years ago, economies of scale hadn't caught up and MicroUSB was used for cost and availability. It was difficult enough to release ANY hardware during peak COVID and absolute chaos and saturation of supply routes. Now it's just being retained for drop in compatibility. If you want there's any number of third party boards with USB C.
Now THIS is interesting. Guess I'll be buying a few to put away for future projects. After your interview, I did get the impression they were considering RISC-V, but I didn't expect it until at least this time next year, so this is quite an interesting surprise. It's not an SBC though, so it's not quite as interesting there. Being a drop-in replacement (assuming it is always that simple) is really exciting though. I'm loving all the RP2040 projects lately, especially in modding game consoles (I just installed one in my Switch last week, in fact), so hopefully this opens up a few more options for those.
The connector is a bit cheaper. The board cost so little it does matter. C would be nice but eh, not that big of a deal, need to have more cables handy when doing anything with it and it's sometimes a hassle, but a couple of seconds of hassle is worth it.
@@mythicalforce8658 Molex 2169900003 type-c and 0475900001 microusb are the same bulk price on digikey. In fact, the type-c is 0,02 cents cheaper but you also need to add a 5.1k resistor so it adds up to exactly the same. Even if it were more expensive I wouldn't give them cost as an excuse.
I love this content! I'm a newbie on microcontrollers and I enjoy tinkering, so learning about new possibilities is something I always look forward. By the way, your channel is so informative, I always find cool stuff! Thanks for sharing and also for being an honest youtuber!
2 ARM cores or 2 RISC-V cores? Faster? 2x Memory? more efficient? Just $1 more than the previous version? That is how you update your Hardware! GREAT job Raspberry Folks! Hardware Companies have to learn from them!
Probably my favorite projects from the Pico are the controllers for various arcade games, like the mai Pico, IIDX Pico, and AIC Pico. Hope that the Pico 2 will help with these!
Thank you for creating this video. I've been using a lot of Raspberry Pi's (mainly zero's) here in my home, and in the last 12 months or so, added Pico's to my collection, because of their price and micropython, which has "grown up". :) I was wondering about the Pico 2 and your video helps me out. Thanks!
Congratulations to the Raspberry Pi Foundation on the impressive achievement with the RISC-V board! Jeff, your dedication in the content to innovation and open-source technology continues to push the boundaries and inspire the tech community. This milestone of the Pi foundation is a testament to RISC V vision and commitment to making embedded computing accessible to all ❤
My personal introduction to the Pi Pico was with the "PiTrex" project, which is a modern Pi powered cartridge for the classic Vectrix system. It really breathes some new life into that thing!
I find it interesting that they decided to have both ARM and RISC-V on a single chip. I feel like one of them could be cut to make room on the silicon for more PIO blocks or more cores of the same architecture I do think it's cool they added RISC-V so you could try it out and then switch over to ARM if it doesn't work for you, but I don't think it's the most practical way to do it.
A lot of 3D Printer MCUs have adopted the RP2040. I think the Toolhead PCB on the Positron you are building has a RP2040 on it. I’m excited to see the RP2350 get adopted and what changes that may bring. Faster, more IO & lower power consumption sounds like seriously positive improvements for toolhead boards and more.
this is amazing to see, i had already seen some pico boards, similar to rpi pico but under risc-v but seeing rpi foundation jump into it is great news, because they have funding and developers to really support the board, make great documentation and make software that actually works, and you dont need to expend days trying to burn the firmware to then have an unstable mess
Oh hey! Thanks for making it, I am happy to have something that improves on EEVBlog's original uCurrent design. Hopefully a few more people see the CurrentWave and pick one up too. Easier to explore microamps with it :)
FYI I read in the specs that it’s not a drop in replacement due to adjusted power requirements and power pinouts, the 70x70 A variant IS however the same size as the 2040 footprint
If you're into retro gaming, one of the really cool use for a RP Pico is as a modchip. It's slowly replacing the old-school modchip because it's so much cheaper, easier to install and to update. The best example is the PicoBoot, which is for the GC. It's basically better on every aspects compared to the old hardware mods because while the more common XenoGC could only let you boot unsigned disc (so you still needed a boot disc to use homebrews and backups and a working drive), the PicoBoot can simply bypass the regular boot altogether, so you only need a SD adapter and you can remove the disc drive if you don't need it. There's also one for the Xbox, which is also apparently better than the old modchip and software mod, but I don't know much about it. There are also a lot of smaller projects, like emulating a Memory Card on the PS1 and letting you boot backups without mods, replacing the memory card of the N64 (which uses RAM and a battery), using one as a programmer to mod an Xbox 360 (a lot cheaper than the ones usually used), creating a cheap flash cart for some consoles, etc. I've even seen some projects for turning one into a capture card for some specific consoles (like the Genesis RGBlast, which convert the RGB signal into USB).
I'm most excited about the extra PIO and double RAM! Now, we should be able to make a really great tilemap/sprite VDP for retrocomputer projects! (It's cool that hobbyists were able to emulate the Yamaha V9958 (MSX 2+) with the original Pico, but even the SNES PPU blows that away.)
They aren't considered a market holder, so probably there will be no problems. I guess that if they could do it cheaper for micro USB I am fine with it. It is already expensive enough as is.
I actually ordered it today, and hoping to get it soon. I've used Pico in most of my projects, it's the best Microcontroller by a long shot. Pico 2's currently on Backorder and I'm expected to recieve it in a month.
Very interesting - I'd love to see a (small) FPGA incorporated in to a future version. I know, wishing for the next version already. For now the inclusion of Risc V cores in to a 'tinkerer' device is not a bad idea... I suspect it was done because Raspberry Pi had some spare real estate post die-shrink - a reason for the lower power draw?
Looks like you missed a very big difference: the ARM cores are Cortex-M33 cores, with floating point and DSP support. That's a big improvement over the Cortex-M0+ of the RP2040.
It's in the on-screen specs in the chart I made, didn't want to dig into the cores themselves in the script to keep things short and to the point. The other thing is I only know top-level things about the Arm core differences, but I have seen M33 cores in tons of devices over the past year, it seems like a very useful core compared to what we had on RP2040, probably easier to hack in Linux-y things too!
Currently daily drive a Unicomp Mini M, it is a tenkeyless buckling spring keyboard that is a modern take on the IBM Kishsaver. The one I have is a revised variant that uses a RP2040 as the controller. It is so crazy to see the RP2040 be used for so many things, it so versatile!
Thank you for mentioning all those projects! I would love to see a whole video dedicated to explaining some of them in more detail. The micro controllers are super neat, but it's difficult to understand their potential unless you invest months of tinkering... Or or just have someone explain it. 😁
You should probably be clearer that the RP2040 version of BlueSCSI is actually derived from the ZuluSCSI project from Rabbit Hole Computing, who have a long standing relationship with the designer of the original scsi2sd project. ZuluSCSI did borrow some file system handling elements from other projects, but the actual SCSI code (and the hardware design) was all down to ZuluSCSI and scsi2sd.
In the fighting game community, the pico is in heavy use in Haute 42 leverless controllers running the gp2040-ce firmware - thought you might be interested in this since you didn't mention it!
“The RP2350 chip on top is also a drop in replacement for the RP2040” Actually this is incorrect! Both chips are 7x7mm QFN but the RP2040 has 56 pins and the RP2350 has 60 pins! I have not yet checked how closely the various pins align or how much work a design upgrade would be, tho I will certainly be doing that upgrade on my motor controllers!
@@JeffGeerling Indeed! I just tagged you on a post on twitter with a side by side comparison of the datasheet pinouts. Things are pretty similar but there are new power pins and things moved a bit, so some care will be needed in layout updates.
I just found this out like couple of hours ago when I got an e-mail about the new Pico 2 with RISC-V. I was like I gotta get a few so pre-ordered 5 along with RaspberryPi 5 8gig! 🤣
My favorite part of this video was the bloopers at the end. I just recently bought some Pi Picos for a project but at the moment I can't remember what the project was.
The on-board Flash options are VERY interesting as it makes it viable to integrate a RP2040 as a truly stand-alone device. Rather than be reliant on the presence of an external flash chip. Combined with the security features + the bigger IO variants and you got something that can actually rival STM32 chips proper in regards of commercial and possibly even Industrial applications (which has been dominantly STM32, PIC and AVR territory). For now though i haven't gotten to figuring out the PIO modules on my RP2040 boards yet. So i'm good.
I'll be curious to learn why only two cores can run at one time, but my initial guess would be some sort of limitation in the bus or memory architecture.
Yeah, the arm and riscv cores share ports on the AHB matrix through simple muxes, so only one can be active on each port at a time (you can have one of each active though).
Awesome news. I really like the RiscV and Arm combo, I think that this shows that Raspberry Pi are on the RiscV for the long-term and we might get a Raspberry pi 6 or 7 with a new CPU.
This is amazing. I had a project which was pulling Sega Genesis RGB feed in via USB and the margins were quite thin. Just that extra clock boost alone will do tons of good, but more than that, I wonder if they've improved the onboard ADC? There was a mostly unpatchable issue with it reporting faulty values in the RP2040.
its so exciting that we are finally starting to retire older technology with newer, more efficient, more powerful stuff! On Linux we replace X11 with Wayland. AV1 replaces x265 and x264 HVEC. RISC-V and ARM slowly replaces x86. Exciting times!
@@PragandSens i still have so many devices relying on mUSB, that i dont really mind the non-USB-C thing. But its coming in the next iteration, i'm sure. otherwise, just buy third-party picos with USB-C when they are available :)
I was at DEFCON 32 last weekend and they announced the chip there by building one into all the badges - very cool (In this case, the chip is being used to run a gameboy color emulator with a custom ROM, along with some LEDs, an IR blaster, accelerometer, and a USB-C charging/flashing port)
Another example of a Pico powered thing is the new production run of Unicomp keyboards. I actually had problems with mine, the board missed a pullup resistor and the keyboard matrix had an inconsistent bridge. Initially I got an old controller but was able to repair the original board too. From which I learned that the Pico controller fixes the keyboard becoming unresponsive when left on a powered USB, though the new firmware. Unfortunately they ended up having to replace the entire board under warranty due to the matrix issue, which we only figured out after fixing the also faulty controller. I'm very happy with this new keyboard though and will probably get the old one serviced eventually, as that would fully fix it.
i have about a dozen picos, i havent done anything with them other than hand out a few to my friends so they can have fun. but YAY im gonna order some of these theyre so beautiful and one day i might be smart enough to use one for other than lighting a lamp. Cheers from Texas!

I'm looking forward to seeing more about that B version, if anything to see what the additional GPIO provides. And of course, because I'm currently working on a project with the Pico W, I can't wait for the W version of the 2 to release as well.
I think Adafruit had the B version on their livestream earlier, first time I'd seen it!
That's a really good idea to include the RISC-V cores *in addition* to familiar ARM cores. That's a beautiful way to lubricate the transition into a new world.
No USB C, though. I wonder why? It is physically larger which is the only reason I can produce to stick with micro USB.
USB-C isn't better than Micro-USB. Micro-USB is cheaper. Micro-USB is easier to solder too.
If you want USB-C, there are tons of ESP32/Arduino boards out there with USB-C. They are the same thing as a Pico.
@@quarteratom skill issue?
Back when Pi Pico was introduced, nearly 4 years ago, economies of scale hadn't caught up and MicroUSB was used for cost and availability. It was difficult enough to release ANY hardware during peak COVID and absolute chaos and saturation of supply routes.
Now it's just being retained for drop in compatibility. If you want there's any number of third party boards with USB C.
Size isn't the issue with USB-C. Waveshare uses a USB-C port in its RP2040-Zero with a fraction of the Pico board's footprint.
I think the main reason for sticking with Micro USB was to keep it as much of a drop-in replacement to the Pico as possible
Now THIS is interesting. Guess I'll be buying a few to put away for future projects. After your interview, I did get the impression they were considering RISC-V, but I didn't expect it until at least this time next year, so this is quite an interesting surprise. It's not an SBC though, so it's not quite as interesting there. Being a drop-in replacement (assuming it is always that simple) is really exciting though. I'm loving all the RP2040 projects lately, especially in modding game consoles (I just installed one in my Switch last week, in fact), so hopefully this opens up a few more options for those.
"There's no way to disable the speaker..."
Red Shirt Jeff begs to differ.
Hammer
There is always a way ... however once disabled, it may not always be possible to re-enable in future.
Why again micro USB? :(
cost!! nothing else!
The connector is a bit cheaper. The board cost so little it does matter. C would be nice but eh, not that big of a deal, need to have more cables handy when doing anything with it and it's sometimes a hassle, but a couple of seconds of hassle is worth it.
just get a pi 5
so that myfriends on Aliexpress could make clones and earn their buck too ;)
@@mythicalforce8658 Molex 2169900003 type-c and 0475900001 microusb are the same bulk price on digikey. In fact, the type-c is 0,02 cents cheaper but you also need to add a 5.1k resistor so it adds up to exactly the same. Even if it were more expensive I wouldn't give them cost as an excuse.
I love this content! I'm a newbie on microcontrollers and I enjoy tinkering, so learning about new possibilities is something I always look forward.
By the way, your channel is so informative, I always find cool stuff!
Thanks for sharing and also for being an honest youtuber!
2 ARM cores or 2 RISC-V cores? Faster? 2x Memory? more efficient?
Just $1 more than the previous version?
That is how you update your Hardware! GREAT job Raspberry Folks!
Hardware Companies have to learn from them!
Probably my favorite projects from the Pico are the controllers for various arcade games, like the mai Pico, IIDX Pico, and AIC Pico. Hope that the Pico 2 will help with these!
So jealous that you got a Radxa x4 already! I've developed this inexplicable love for everything N100 recently. Can't wait for the vid, man!
Thats interesting. Can't wait for the w-version.
I always enjoy outtakes, please more of that 😄
I dont think the average computer engineer realizes how awesome these pico chips are.
great timing but I guess we need to wait for pico 2 W... (for WiFi connectivity)
Preordered 2 of these 10 mins ago and the video is already here! Yay!
Thank you for creating this video. I've been using a lot of Raspberry Pi's (mainly zero's) here in my home, and in the last 12 months or so, added Pico's to my collection, because of their price and micropython, which has "grown up". :) I was wondering about the Pico 2 and your video helps me out. Thanks!
I loved the bloopers at the end, amazing! 😆
Thank you Jeff for this video. Pico 2 is a great addition. I'm sure this little thing will be a champion in the Pi universe!
Congratulations to the Raspberry Pi Foundation on the impressive achievement with the RISC-V board! Jeff, your dedication in the content to innovation and open-source technology continues to push the boundaries and inspire the tech community. This milestone of the Pi foundation is a testament to RISC V vision and commitment to making embedded computing accessible to all ❤
Raspberry Pi Ltd, not the Foundation.
My personal introduction to the Pi Pico was with the "PiTrex" project, which is a modern Pi powered cartridge for the classic Vectrix system. It really breathes some new life into that thing!
I find it interesting that they decided to have both ARM and RISC-V on a single chip. I feel like one of them could be cut to make room on the silicon for more PIO blocks or more cores of the same architecture
I do think it's cool they added RISC-V so you could try it out and then switch over to ARM if it doesn't work for you, but I don't think it's the most practical way to do it.
Heat shrink on the alligator clips holding the board will be appreciated.
Heh you don't like scratching them up like that? :D
One thing I love about rpi is how consistently the new versions are drop in. It’s good and thoughtful design
A lot of 3D Printer MCUs have adopted the RP2040. I think the Toolhead PCB on the Positron you are building has a RP2040 on it. I’m excited to see the RP2350 get adopted and what changes that may bring. Faster, more IO & lower power consumption sounds like seriously positive improvements for toolhead boards and more.
Oh hello 😁
I totally forgot about the 2040s on the Positron, lol. adding the mainboard to the base plate tomorrow!
That's really cool, Jeff. You have the spirit of an educator.
Have been using a Pico for half a year as a microcontroller for a Guitar Hero guitar controller thanks to Santroller. The Pico is incredible.
I somehow didn't expect the Pico 2 despite the fact that my work's supplier discontinued a few Pico SKUs about a month ago. This is the best news!
this is amazing to see, i had already seen some pico boards, similar to rpi pico but under risc-v but seeing rpi foundation jump into it is great news, because they have funding and developers to really support the board, make great documentation and make software that actually works, and you dont need to expend days trying to burn the firmware to then have an unstable mess
Wow m a big fan of your content. It was an honor seing CurrentWave D on your bench 😊
Oh hey! Thanks for making it, I am happy to have something that improves on EEVBlog's original uCurrent design. Hopefully a few more people see the CurrentWave and pick one up too. Easier to explore microamps with it :)
FYI I read in the specs that it’s not a drop in replacement due to adjusted power requirements and power pinouts, the 70x70 A variant IS however the same size as the 2040 footprint
True, missed that in my reading of the specs!
If you're into retro gaming, one of the really cool use for a RP Pico is as a modchip. It's slowly replacing the old-school modchip because it's so much cheaper, easier to install and to update. The best example is the PicoBoot, which is for the GC. It's basically better on every aspects compared to the old hardware mods because while the more common XenoGC could only let you boot unsigned disc (so you still needed a boot disc to use homebrews and backups and a working drive), the PicoBoot can simply bypass the regular boot altogether, so you only need a SD adapter and you can remove the disc drive if you don't need it. There's also one for the Xbox, which is also apparently better than the old modchip and software mod, but I don't know much about it.
There are also a lot of smaller projects, like emulating a Memory Card on the PS1 and letting you boot backups without mods, replacing the memory card of the N64 (which uses RAM and a battery), using one as a programmer to mod an Xbox 360 (a lot cheaper than the ones usually used), creating a cheap flash cart for some consoles, etc. I've even seen some projects for turning one into a capture card for some specific consoles (like the Genesis RGBlast, which convert the RGB signal into USB).
Never expected a drop-in replacement. This is awesome!
1:12 the rp2350 is not a drop in replacement for the rp2040 unfortunately. The 2040 is a qfn56 and the 2350 is a qfn60.
Can’t wait for the wh version
I'm most excited about the extra PIO and double RAM! Now, we should be able to make a really great tilemap/sprite VDP for retrocomputer projects! (It's cool that hobbyists were able to emulate the Yamaha V9958 (MSX 2+) with the original Pico, but even the SNES PPU blows that away.)
Nice! You are also watching the Guy with a Swiss accent with a new episode and fresh ideas around sensors and Microcontrollers 🙂
I read the title as intended and the pun was glorious.
The EU must be really angry that they still didn't switch to USB-C 😂
as **the** EU, I am, in fact furious
They aren't considered a market holder, so probably there will be no problems. I guess that if they could do it cheaper for micro USB I am fine with it. It is already expensive enough as is.
EU requires only standard plug. They don't say which standard.
@@uis246 Also, AFAIK, that regulation only applies to devices with rechargeable cells inside.
Everyone is
Thanks for the bloopers at the end. I was sitting here wondering if I would be able to nail specs like that. I guess we're all human.😊
I actually ordered it today, and hoping to get it soon. I've used Pico in most of my projects, it's the best Microcontroller by a long shot. Pico 2's currently on Backorder and I'm expected to recieve it in a month.
No usb c 😢
it surly cant be costier
It’s mind blowing
It looks like they did it for backward compatibility. It seems logical
@@biblbrox but micro-b usb breaks so much
No problem. There are other boards with the same chip and USB-C.
Thanks for the insightful video Jeff.
Thanks Jeff. Raspberry Pi really should be giving you a salary. I've bought so much stuff thanks to you.
Sorry not sorry!
But also, it's good they don't pay me because then I couldn't talk up other things I like without some amount of bias!
Drop in replacement you say???? Onboard flash and secure boot are MAJOR additions. Very exciting!!!
I promise I'll get to Axe Effect at some point. It's been sitting to the right of my keyboard for a month now lol :D
@@JeffGeerling We're hoping to have a PoE version announcement in October. I think you'll be VERY interested in seeing that one 🙂
@@CraftComputing Indeed, that's the killer app, no need for an extra wall wart and micro USB cable (they're harder to route to precise size!
4:06 GOD DAMMIT IT'S PRONOUNCED "ZED-X SPECTRUM"!!!
Anyways, great video as always dude!
Cortex M33? You mean we finally get hardware FPUs?! WOOOT!
I'm looking forward to seeing what people do with these. Console mod chips made with the original have been LITERAL game changers. It's gonna be epic.
Well I was expecting builtin flash, but still, its is huge improvement over the original pico.
Awesome video 😀
Thanks👍
Very interesting - I'd love to see a (small) FPGA incorporated in to a future version. I know, wishing for the next version already.
For now the inclusion of Risc V cores in to a 'tinkerer' device is not a bad idea... I suspect it was done because Raspberry Pi had some spare real estate post die-shrink - a reason for the lower power draw?
I've been looking forward to this, and really pleased that it's pin compatible.
Looks like you missed a very big difference: the ARM cores are Cortex-M33 cores, with floating point and DSP support. That's a big improvement over the Cortex-M0+ of the RP2040.
It's in the on-screen specs in the chart I made, didn't want to dig into the cores themselves in the script to keep things short and to the point. The other thing is I only know top-level things about the Arm core differences, but I have seen M33 cores in tons of devices over the past year, it seems like a very useful core compared to what we had on RP2040, probably easier to hack in Linux-y things too!
As always..... Great content Jeff! Thank you.
Hi Jeff,
The rp2350 is not the same pinout as the rp2040 and is not a drop in replacement.
(rp2040 was QFN-56 and rp2350 is QFN-60/QFN-80)
0:45 what's the *rentWave gadget. Reminds me of a burden voltage gadget...? Is this measuring current draw in series?
It has switchable resistors to allow you to measure the current through a multimeter down to the nanoamp-check out dothediy.com!
@@JeffGeerling Thanks Jeff, yes I thought it looked similar to Dave's uCurrent, which I have. The little OLED on this is pretty neat though!
Currently daily drive a Unicomp Mini M, it is a tenkeyless buckling spring keyboard that is a modern take on the IBM Kishsaver. The one I have is a revised variant that uses a RP2040 as the controller. It is so crazy to see the RP2040 be used for so many things, it so versatile!
Thank you for mentioning all those projects! I would love to see a whole video dedicated to explaining some of them in more detail. The micro controllers are super neat, but it's difficult to understand their potential unless you invest months of tinkering... Or or just have someone explain it. 😁
Anything RISC V- Hooray! I'm just basically a spectator, glad to see anything moving tech in an open direction.
I'm so hyped about getting a bigger package with more pins.
You should probably be clearer that the RP2040 version of BlueSCSI is actually derived from the ZuluSCSI project from Rabbit Hole Computing, who have a long standing relationship with the designer of the original scsi2sd project. ZuluSCSI did borrow some file system handling elements from other projects, but the actual SCSI code (and the hardware design) was all down to ZuluSCSI and scsi2sd.
In the fighting game community, the pico is in heavy use in Haute 42 leverless controllers running the gp2040-ce firmware - thought you might be interested in this since you didn't mention it!
thanks for the out takes Jeff , also the great info
“The RP2350 chip on top is also a drop in replacement for the RP2040”
Actually this is incorrect! Both chips are 7x7mm QFN but the RP2040 has 56 pins and the RP2350 has 60 pins!
I have not yet checked how closely the various pins align or how much work a design upgrade would be, tho I will certainly be doing that upgrade on my motor controllers!
Oh, I missed that-thought they were identical but I didn't look close enough-there are four extra pins!
@@JeffGeerling Indeed! I just tagged you on a post on twitter with a side by side comparison of the datasheet pinouts. Things are pretty similar but there are new power pins and things moved a bit, so some care will be needed in layout updates.
I just found this out like couple of hours ago when I got an e-mail about the new Pico 2 with RISC-V. I was like I gotta get a few so pre-ordered 5 along with RaspberryPi 5 8gig! 🤣
My favorite part of this video was the bloopers at the end. I just recently bought some Pi Picos for a project but at the moment I can't remember what the project was.
The on-board Flash options are VERY interesting as it makes it viable to integrate a RP2040 as a truly stand-alone device. Rather than be reliant on the presence of an external flash chip. Combined with the security features + the bigger IO variants and you got something that can actually rival STM32 chips proper in regards of commercial and possibly even Industrial applications (which has been dominantly STM32, PIC and AVR territory).
For now though i haven't gotten to figuring out the PIO modules on my RP2040 boards yet. So i'm good.
I'll be curious to learn why only two cores can run at one time, but my initial guess would be some sort of limitation in the bus or memory architecture.
Pretty sure it's the IO bus. Technically you can run one of each cores together. I haven't tried though!
Yeah, the arm and riscv cores share ports on the AHB matrix through simple muxes, so only one can be active on each port at a time (you can have one of each active though).
Awesome news. I really like the RiscV and Arm combo, I think that this shows that Raspberry Pi are on the RiscV for the long-term and we might get a Raspberry pi 6 or 7 with a new CPU.
Would be interesting if the RiscV and ARM cores are just separate instruction decoders and otherwise share the ALU and other internal gubbins.
I love the Pico can't wait to get a look at Pico 2.
Typ C for the win....
.......I guess Soldering it is
Every USB-C port I've seen has different pads, even those that are only pinned for 2.0. So good luck.
This is amazing. I had a project which was pulling Sega Genesis RGB feed in via USB and the margins were quite thin. Just that extra clock boost alone will do tons of good, but more than that, I wonder if they've improved the onboard ADC? There was a mostly unpatchable issue with it reporting faulty values in the RP2040.
Supposedly it's better, but I am not qualified to test it or confirm that!
its so exciting that we are finally starting to retire older technology with newer, more efficient, more powerful stuff!
On Linux we replace X11 with Wayland.
AV1 replaces x265 and x264 HVEC.
RISC-V and ARM slowly replaces x86.
Exciting times!
Yes but where is it the microUSB replacement for USB-C
@@PragandSens i still have so many devices relying on mUSB, that i dont really mind the non-USB-C thing. But its coming in the next iteration, i'm sure. otherwise, just buy third-party picos with USB-C when they are available :)
I was at DEFCON 32 last weekend and they announced the chip there by building one into all the badges - very cool
(In this case, the chip is being used to run a gameboy color emulator with a custom ROM, along with some LEDs, an IR blaster, accelerometer, and a USB-C charging/flashing port)
Another example of a Pico powered thing is the new production run of Unicomp keyboards.
I actually had problems with mine, the board missed a pullup resistor and the keyboard matrix had an inconsistent bridge.
Initially I got an old controller but was able to repair the original board too.
From which I learned that the Pico controller fixes the keyboard becoming unresponsive when left on a powered USB, though the new firmware.
Unfortunately they ended up having to replace the entire board under warranty due to the matrix issue, which we only figured out after fixing the also faulty controller.
I'm very happy with this new keyboard though and will probably get the old one serviced eventually, as that would fully fix it.
Oh, I've just got the pun in the title. Yeah it's a risky bet!
raspberry pico is also big in game controller scene. A lot of fightbox, arcade stick, game controllers are based on RP2040.
So I'm finding! And some custom keyboards.
i have about a dozen picos, i havent done anything with them other than hand out a few to my friends so they can have fun. but YAY im gonna order some of these theyre so beautiful and one day i might be smart enough to use one for other than lighting a lamp. Cheers from Texas!
