A really condensed version of the 'original' 3hr-long KiCad + STM32 PCB design video. This time using a different MCU with minimal peripherals. As mentioned in the video, it would really help me out if you could fill out the brief survey regarding a paid PCB-design course: bit.ly/3pPgXym
Additionally, if you'd like to support the channel even further, I have a Patreon page set-up: www.patreon.com/phils94
Thanks again for watching - next video will be on 'FIR Filter Design and Software Implementation'! :)
tnx a lot sir.....
This channel quality is superb. Thank you Phil, we appreciate your hard work
Thank you so much, Mikåel - very glad to hear that! :)
I really like how simple you're projects are here in these videos, it makes it super approachable and easy to digest. Thank you.
I'm glad you like the format, thank you!
Congrats on 20K Phil! Have been watching your vids for some time now, they never let me down! STM32 is always fun, I've been focussing on ESP32 lately, also very fun! Great little chip for IOT projects. Cheers
Thank you very much, Christiaan! I've actually never played around with ESP32, probably should because lots of people keep mentioning them!
This video was so detailed and a complete story from idea to manufacture. This is exactly what I have been wanting to find. Thank you for this.
And also, thank you for no loud, annoying intro and out-tro music. ;)
I am starting to learn STM32 and your videos are GEM!!! Thank you!!
That's great to hear, thank you!
Just recently discovered your channel and I have to say you really are crushing it. Quality is way up there!
Thank you very much, Manuel!
I just want to thank you this extremely useful tutorial. I haven't downloaded any of your files, but I followed what you did in the video step by step and with tiny modifications I made a similar STM32 board. You compressed a huge amount of information into this video without making it hard to understand. The footprint assignment part was particularly useful for me because I had no prior knowledge on that topic. Once again, thank you for this informative and well-structured video!
Thank you very much, very glad to hear your feedback!
Hey Phil, as so many others here have already said: Great work!! Keep on making these kinds of videos, they are a gold mine for beginners. I am currently building a sensor to count people passing through a door and need it built as a PCB. Your video on the breakout board for the STM32 taught me everything I needed to know to get started with KiCAD, and on top even new things about circuits I did not know. There was so much information in so "little" time (Yeah 2.5 hours is not too little, but anyways). I hope to be able to support your channel at some point
Hey Joel, Thank you very much! Very glad to hear that the videos have been useful. Hope all goes well with your new PCBs! :)
Extremely useful, as always. It is even better to watch this video in context with the other STM32 design with Kicad videos.
Thank you very much, Juanjo!
I'm going to re-build this simple board as it is the best way to learn and then double check it against your Github. Should be my first order with JLCPCB. I will definitely let them know I came from here, you deserve all the support you can get for this outstanding channel!
That's awesome, Jasem. Thank you for letting JLCPCB know that you've come to them from this video! :)
As student of electronics i really enjoy watching your videos. I learned a lot , thanks again.
Awesome, thank you for watching, Jan!
Perfect video for those getting started with custom stm32 boards
Appreciate this Phil, really helped clear up some things I was uncertain about using STM32 datasheet and reference manual. Used your tutorial to make a breakout board for a simpler STM32 TSSOP-20 for my microcontrollers class. Also appreciated your "small" comments and pro tips along the way like ferrite bead, one decoupling cap per VDD pin, etc. Thanks a lot!
Thank you very much for your kind comment, Luke!
Your channel has been GROWING! :) your content is quality man. Keep it up, 100k is coming soon
Thanks a lot, Corne! Haha 100k would be the dream :D
Phil, thank you so much for your work here. You have helped me immensely!
I'm very glad to hear that, thank you for watching!
Thank you for all you do, Phil! 👏👏✌
I'll pay for the course for sure! Extremely helpful and valuable to engineers and makers alike.
Thank you very much for your support! Hopefully the course will be helpful, definitely going to put quite a bit of work into it :)
@@PhilsLab has the course com up . if so please provide the link
Thank you for taking the time to make videos like these. You are filling a void of information on this subject.
Thank you for watching! :)
Thank you so much Phil! You're really helping me out with these tutorials 🙏🏼
Awesome, thank you for watching!
This is outstanding content. Thank you, Phil!
Thank you very much, Are!
I like how you cover things like power filtering, decoupling capacitors, impedance matching. Since I’m not an electrical engineer, these are things I wouldn’t think of unless pointed out to me.
I'm glad to hear that, Mark. Hopefully the next couple videos will cover more things like that!
Never done PCB design, but I like to learn it some day. This was very beginner friendly, you've clearly explained what you did and why you did it. I'm going to re-watch and try to mimic it by myself, thank you! :) It's insane you can order 5 ready assembled boards you've design at home for just $30.
Thank you, for watching! Very glad to hear your positive comments - hopefully your own PCB design goes well :)
Used the exact same MCU for a breakout board I designed, using your design guidelines shown in the STM32F4 video lol. Thanks for all the tutorials mate.
Awesome, thank you for watching, Suva!
This looks like a really useful project.
Phil, great content as always. Do you think you could do a video about how you develop bootloaders for your boards? I think it could make a great middle segment between the hardware design and the actual applications being run.
thank you! all your videos are top notch!
Thank you very much, Jan!
Great tutorial, keep up the awesome content!
Thank you very much, Nader! Definitely more to come! :)
Great video, amazing information, you make everything look so easy... thanks!
Thank you very much, Ron!
I really like the way you describe the things.
Thank you, Bhim.
Thank you for the amazing content. I wouldn't mind paying your PCB Design course. :)
Awesome, thank you, Mahesh!
Excellent work buddy
Thank you!
Great content Phil, as always..
Thank you very much, Jithin!
Keep up the good work man 100k subs soon
Another excellent video!
Thank you, Peter! :)
Very good tips, thank you.
Just fell on this video. Excellently done.
Thank you!
Awesome video, thank you so much
Great content Phil.
Thank you, Daniel!
Nice video. I also find it handy to set the direction on Kicad's schematic labels.
Thank you, Stephen - yes, that's a good thing to add!
Tutorial quality is rising. thanks for sharing with us.
Thank you for watching, Kursat!
Again, great tutorial...cheers.
Thank you, Andy!
Great content! I was really surprised to see the STM32F1 Chip not having a big thermal pad on the bottom
Thank you, Peter! Yeah, I think you maybe can get the STM32F1 chips in some form of QFN package and they should have that. Never seen it on LQFP though.
Awesome quality !
Thank you!
Phil, if you connect the USB resistor to an output, you can force reenumeration on reset by bringing it low for a short time. This would avoid the need to reconnect the USB cable when downloading a new firmware version.
Very good content.Thank you
Thank you very much, Julio!
Awesome video, thank you. It will be interresting to show the board and a small program running on it.
Thank you, Marco! Yeah, I'll see if I can get these boards made by JLCPCB and show them in a future video.
please make a series in wich you explain stm32 basics like blinking a led. I really like your videos and I think you can explain everything very well.
Thank you! I'd recommend checking out my 'STM32 Programming Tutorial' where I cover things like RGB LEDs, SPI, etc.
Hey just a suggestion. I have been following the channel over 2 months i think. I have some experience with KiCad but in the initial days I really struggled. I think It would be a very nice idea to make a playlist of a kicad software course kind of video series. More about of learning KiCad.
Thank you very much for this course in short and extended length, as well all your other tutorials!
I use it as starting point for own STM32 layouts; really helpful.
Just one minor note (even if it does not matter, since the oscillator is symmetric): PB5 (OSC_IN in the data sheet) is labelled as HSE_OUT in your layout, and PB6 (OSC_OUT) is your HSE_IN. Is the change IN/OUT intended (e.g. because OUT from osc view is IN for the MCU and vice versa?)?
A PCB-Design course would be amazing. Even if paid.
Awesome, I'm glad you think so - thanks!
looooove these videos
Thank you!
Hey thanks for the many tips here, both electrical and layout related. I didn't know about JLCJLCJLCJLC marker to inform JLC where to put the serial number.
Thanks for watching, Craig! Yeah, I think the 'JLCJLCJLCJLC' can be useful for saving a couple $ per order!
THankyou! Its a beautiful video. I would really like to see you doing routing in the video!
Thank you, Sumedh! Yes, I'm afraid to keep it very short I had to skip showing that part. But future videos will hopefully be a bit longe r:)
i fucking love you brother. again thank you! helped me out break into pcb design coming from strictly breadboarder world with my stm projects! you rock brother!
Thanks a lot man!
Thank you
Great video! Don't know if this was answered somewhere else, but why did you choose 8 MHz Crystal? I've seen several designes going for both HSE and LSE crystals, one 24 Mhz and a 32.768 KHz one, so wondering how to select the crystal frequency?
you are a hidden gem
Thank you, Ronaldo!
Good video. Looking at the repository, it looks like schematics are blank and no .cmp mapping present? Planning on learning by walking through in detail...
Excellent thank you
Thanks for watching, Paul.
thanks for tutorial, I still learn about PCB design and I have question, why is no ground trace in TOP layer?
Hi Phil, great channel, I've been watching for a little while. I have a quick comment about the layout. I'm guessing the USB connector sits on the PCB. You have the grounded USB connector above the +3V3 rail with just solder resist in between. OK you've not connected the shield but it will probably be connected at the PC end.
Great video, I'd like to see results of assembly.
Thanks for sharing, great video as usual. Could you please make a tutorial on adding video processor to arm microcontroller to drive an LCD display ?
Thank you very much! I think there should be quite a few videos on how to hook up an LCD display to an MCU around, so probably won't be covering that, sorry!
Thnx for your videos :)
Thank you for watching, Hakan!
cool and inspiring video :)
Thank you!
Thank you for video.
Thank you for watching, Piotr!
Thank you a lot man
You're welcome!
Hi Phil, Thank you for the wonderful video. Can you give some guidelines on when can we use the internal clock of STM32 and the external oscillator for STM32?
he told in 4:12 and 4:36 that you need external crystal oscillator when you need a precise timing
What component/footprints did you use for your micro-usb connector? Really struggling to find a USB connector with a readily available footprint... do people typically just make their own footprint for things like this? I get the feeling I'm not looking in the right place since this seems like it would be a pretty common component. Thank you for the fantastic video!
Hey Phil, wondering why no USB ESD protection like your other layouts?
Great tutorial. You are a hero.
I wonder if you can do videos on advanced high speed stuff. (HDMI, DDR...etc)
Thank you, Kadhem! Yes, I'm planning on making a video on an FPGA design which includes HDMI and DDR.
thank you for this. have a question. do you now where I can get costume membrane switch made, tactile and non-tactile for low price?
Can you do a STM32 BGA? Would be interesting, maybe with external RAM and Flash
Could you do a tutorial on how to make a pcb with an STM32 + DRV8323 and show us the step to control a bldc motor?
Does the ferrite bead (FB1) also help with limiting the current on connecting to USB? A board I recently designed causes my STLink and UART-Bridge to disconnect whenever I connect power to the board and I have the suspicion, that my design draws too much current, because after that it works fine.
Did you program it directly through D+ and D-?
Finally, a "blue pill" with working USB. I think a lot of people know the situation with the Chinese boards.
I have one remark ( it's not that important but I see you use it throughout your videos), you always say that the Boot0 pin puts the board in bootloader or not. This is true but I would rather suggest using the terminology from the technical reference which is, that the Boot0 pin just jumps to the system memory part of the board. Why do I have this suggestion? Because the user can overwrite that memory if it wants. By default, the chip comes with the bootloader in that memory section so you can flash it via UART1, but I can overwrite it if I want.
It's a small suggestion, not that important. Great video, really condensed but contained all the details necessary! And I responded to the survey as well, hope to see a course soon enough.
Hi sir, I have one question about that.
Can I program the STM32 with the SWD connexions without pulling the Boot0 up? I undestand that it's the way to do it, but I would rather confirm it before trying.
Nice video! Thank you
Thank for your great tutorial, but i can't open the sch file in the github repository
Hi Phil, What do you think about make a video for ADS1256+STM32. I think its most useful for us. Thank you for this video and your hard work.
❤️learn pcb layout design
Decoupling
Thanks for your videos, I find them very educational for my hobby. Just to let you know: the github tarball seems to have been messed up slightly. The schematic has been replaced by a blank page. Luckily there's still a backup schematic file in the set containing what looks like the correct drawing.
Thank you! And thanks for pointing that out, yeah I don't know what went wrong there.. I'll be fixing it soon!
Could a Crystal Resonator be used instead of the Crystal Oscillator? JLCPCB has some as basic parts with smaller footprints.
Phil, what would happen if I do a top copper pour of 3V3 (top copper plane with proper isolation for rest of the traces)? Is this good practice?
Excellent videos. Keep it up. You once did a design on RF circuits. Could you design a PCB with an on board antenna (PCB trace) like on the common ESP32 or ESP8266 microcontrollers? I really would love to see how this can be done.
Thank you for watching!
Yes, I've had a couple of requests for on-board PCB antennae. It's quite a large topic and one that typically requires (fairly expensive) simulation software, so not sure I'll be doing anything on that anytime soon - sorry!
Hi Phil, is it a bad practice to route pcb traces under an IC? I see you haven't done that, but I do most of the time for convenience.
Thank you very much Phil for introducing me to STM32 microcontrollers. For some projects I had in mind Arduino wasn't cutting it anymore, and now I am designing my first STM32 board. I think it's an awesome alternative to arduino, but with a whole lot more power and options to choose from. I would love it if you could make an example in which you interconnect two processors on the same board to expand I/O (Let's say one with LTDC controlling a display, and the other one doing the data processing and gathering the data that has to be displayed through the other controller). I am now using the STM32F746BGT6 (LQFP 208) to do a controller for a very large aquarium with sensors and 24bit ADCs all over the place, and an LCD touchscreen display to show temps and configure some things. It's 12$ a piece and I think I could have done with two cheaper ones without driving any of them to the limits. Just can't figure out how to do it from the datasheet, and you explain things so crystal clear I would love it if you would show us how that's done. I think you did it for the flight controller but you don't go into much detail about that. Thank you very much!
Why do you need 24 bit ADCs for an aquarium?
Another Awsome video but I think you forgot to mention before going to PCB layout that Netlists need to be generated ... Great videos on your Channel Keep up the good work!
Thank you, John! I don't actually generate netlists anymore but rather import directly in PCBnew from the schematic, but yeah should've mentioned that!
How do I set the parameters so that I don't have to keep changing the size of the vias and track widths when I add a new ones?
Thanks a lot.
Thanks for watching!
Can someone explain what the boot0 physical component is? In the 3d demo, B0 doesn’t look like it’s connected. I’m assuming it’s something we’ll have to hand solder? But what is it? Also with the usb, is it a usb A or usb B? How should I choose that
would this be done the same way for the STM32H757BITx (LQFP208), or would i need separate power and crystals for each parts of the chip
Why not using the filtered 3.3VA for everything as opposed to just the analog section?
mr phil, i'm trying to learn how to just make ADAPTERS with kicad and have them made so i can put connectors on a board. like just a USB front panel device, so it's not electronics - it's 18 pins to 18 pins. what should i learn or watch to just get simple pcb's where i surface mount conectors and recepticles designed in kicad?
Which regulator would you suggest if i want to get 3.3v from 9v battery current requirements are 200mA. Do you think it would be efficient to use the same voltage regulator as you have used ?
Phil, i wasn't sure if the $33.10 was per unit for 5units, or the total for 5 pcs.?
Thanks for a nice 'walk-through '
Can some one help me with what pins are used for programming? I’m assuming usb is only for powering? I don’t see st link connectors on the schematic
Great !!!!!!!!!!!
Thank you!
If you put a course I will pay for it provided it's in Kicad. It will be icing on top if there is RF design basic knowledge in it. I love Criss Gammels course too. But I owe you a lot to pay for it.
Thanks Paul, yes it'll be with KiCad! Right now I'm thinking of a mixed-signal board (analogue + digital), USB high-speed, and some more interesting stuff.
Good work keep it up , if you can show us how to communicate with STM32 processors using USB it would be great ! 👍
Thank you, Yaman! My video on STM32 Programming contains a bit on how to communicate with STM32s via USB, if that's what you're after?
@@PhilsLab nice then i will definitely watch it , i hope your channel will get more popular as soon as possible so it will be worth your time , keep the good work :)
Your channel is flawless, you really do explain everything we designers do at every stage (in my case I dont use jlcpcb assembly but thats a detail). Im so excited to hear you are making a course with Robert Feranec, hopefully it could give some kind of certificate or such, ill be waiting for more news on that!
Thanks as always!
Thank you very much for your very kind words!
Yeah, definitely would like to include the option of giving a certificate upon completion. Will hopefully get the course made in the next month or two :)
@@PhilsLab cool!, Im completly down on taking that one, I will be waiting
