Thanks Lee for another new add-on for the Raspberry Pi V….well you can always cobble together a cup warmer for your tea or coffee if the V can’t handle the extra wattage…😂!
Have a great day!
Here's an idea to use extra power: Addressable LEDs. People do elaborate lighting projects with them, and often need extra power past what a Pi can provide. Motors and servos can also be power hungry.
Super cool desktop background
Nice, I just changed to an NVMe board using gpio pins, serendipity:)
tl;dr -> extra power used for output pins; pi still gets only 25w
I was curious about the uses of this board when I saw it on their 52pi website. I think I can put some pieces together now.
First, on their images of the board on their website, they state the usb-c output port only provides 5.1v @ 5a -> 25w. So, they are only supplying the standard 5a to the pi if you power the pi via their cable (or yours). It makes sense if you think about it - the traces on the pi’s circuit board can’t handle more current than they’re designed for. And the usb ports have their own standard limits. Although your testing probably proved that some power is stolen from them by the pci-e port.
Second, I think the main purpose of the 8a output is to supply power via the 5v pins, or the 5v pads on the board where you could solder your own wires. That additional juice could be used to run a bunch of relay boards (power to the relay power pins, while the signal still comes from GPIO pins). Or you could run fans from the power. Or even supply power to your external drives (with the right wiring). Powering sensors. Powering servos. Etc. Etc. All while proving a common ground for both the power line and the signal line if the two originate from both boards independently.
This is all an educated guess. I don’t have this board, and I’m only going by the pics of it on their website, but I’m betting we’ve solved part of the mystery. 😊
I appreciate that you've said it's an "educated guess" but all that you describe in terms of electronics interfacing to pins is do-able on a Pi Pico, ESP32 or Arduino board, without the need for a heavier power supply anyway. If I am powering relays or servos, then I am usually doing it from a separate supply which the micro-controller just instructs to switch on or off as necessary.
I don't understand the need for such a heavy power delivery on the Pi anyway but, as I've said previously several times on here, the Pi (and SBCs in general) have completely lost direction now they are more expensive than just buying a used SFF PC on your favourite auction sites.
From the images on the 52pi official website, the board's 5V/8A output should only provide 5A to the Pi, with an additional 3A reserved for an ATX 4Pin output, possibly intended for other high-power HAT stacking.
“With great power come great responsibility....”
Me: gathers every possible gadget to hook up to the pi 😂
I just ran into this issue yesterday with my old 1 tb 2.5 HDs plugged into a Rasp Pi 5 with NVME board. Just wanted to see what was on the drive. No bueno. CLicking and maybe destruction? Yikes. WIll got back to USB banks with power supply. Good video, thanks!
You could connect some 5v rgb leds strips and pull some more power to test the delivery.
I may have to get one of these to play around with. I use a usb powered screen for my pi arcade machine, the controls connected via usb, and have all the games on an nvme but I’ve never really had a problem with the official 27 watt power supply. I even have it overclocked with no problem. Maybe I could reach the power limit if I added some leds to the gpio pins as well. It would be nice to find the power limit of the pi 5 and see if this board helps at all.
oh yea rite mate
I have ryzen7 5800x pc nvidea 3060 and mainly for steam gaming only 2020 last intel i3 Mac mini 32 gb ram 3.7ghz for productivity with sonoma and 8 gb pi5 256 nvme Ubuntu 23.10 I am after an audio sound card for the pi5 what would you recommend….your videos are a blessing and thank you
I have the same power issue with SDR radio on usb3-2 on Pi5 with nvme. But the same SDR works on Pi4.
What operating system do you use on the computer with the cool raspberry pi on a bike pc?

Plz do a MAAS demo with this
Uhmmm… very weird… I have been using my Raspberry Pi 4B as a NAS with OpenMediaVault on it and I have never experienced this issue. The OS is running on a Samsung SSD 840 Pro and the storage is a portable 4TB WD HDD. Both are connected to the USB 3 ports of the Raspberry Pi. The power supply is the official 5V 3A for the Raspberry Pi 4B.
you may try a 5G pcie modem module in this case … interesting
That usb limitation really is a pain. My old Pi4 could never handle two external drives without crashing. Seems the Pi5 is no better 😒
That seems like a design flaw, the pcie pulling all its power from the USB.
Then again, as mentioned.
Most people are no longer using the older tech. I myself switched to USB 3.0 ssds and nvmes, but not that long ago.
It was just last night I was testing the Argon40 nvme with a 3.0 ssd and portable monitor to see if I could run it all from a power bank.
It worked well!
But you've just described what is essentially a "laptop" device, which you can buy "ready made" with its own internal battery already installed and in a format that is designed as portable - as opposed to having to put the bits together yourself in some kind of portable format.
Again, this proves my point that $35 SBCs as they appeared 10 or 12 years ago were great little "throwaway" devices to teach kids programming on or put on an electronics workbench. But now they've doubled and trebled in cost (not to mention having to pay extra for cooling, cases and power supplies) then the economics of them no longer work.
By the time you've added up the cost of the components as you've purchased them (screen, powerbank, etc.), you might as well just go and pick up a used Lenovo, Dell or HP laptop from a refurbisher for the same (or less) price.
@terrydaktyllus1320 I can agree to some extent. Yes, 10 years ago, the pi was great at about 35 to 40 bucks. Passive cooling and a mere 800 mhz processor.
However, it was their success that pushed the market to what it is now. With dozens of companies making more powerful sbcs than the pi. It has come down to the support and the need to stay in the race.
For me, a pi is my daily driver. I have a number of them. The pi3b is still an impressive little unit...
Compare now how much inflation has pushed your bills up from 10 years ago, and really the cost hasn't changed all that much.
I have a cheap Lonovo, and it is a great little laptop.
The end goal is to make something with a pi, in my opinion.
I am still working on my programming skills...
@@grimsage4495 "I can agree to some extent. Yes, 10 years ago, the pi was great at about 35 to 40 bucks. Passive cooling and a mere 800 mhz processor."
Yes, that was the original design ethic - a cheap programming platform for kids that could also sit on an electronics workbench for prototyping. If you broke it, it didn't matter too much. We agree on that.
"However, it was their success that pushed the market to what it is now. With dozens of companies making more powerful sbcs than the pi. It has come down to the support and the need to stay in the race."
Again, we absolutely agree here - but that's the core problem also. Raspberry Pi has been a "victim of its own success" in becoming a "near consumer" device. The issue there is that it has just created a whole load of newbie users who don't actually know how to build computers to do clever things - they just follow YT step-by-step tutorials, they don't know how to work independently of those.
If you stuck an Orange Pi or used SFF PC in front of them and said "put Linux on them", they wouldn't have a clue how to do it. A lot of them don't even know how to search YT for tutorials. Look at how many "can you now make a video about..." comments that he gets here.
The same people were whining during the epidemic about not being able to buy Pi's when there were plenty of Orange Pi's and used SFF PCs for sale (due to Windows 11 upgraders) that act as equal, or better, alternatives. But these wouldn't know how to use them, hence the whining.
"For me, a pi is my daily driver. I have a number of them. The pi3b is still an impressive little unit."
Again, we agree. The Pi 3B was still $35 and I have lots of them up to that model (and Orange Pi, Banana Pi, Nano Pi, Tinkerboard, etc.) I have a couple of Pi 4's and one Pi 5 because, as a subscriber to The MagPi magazine, I got an offer to get one of the first Pi 5's - but I've done nothing with it because I am doing everything on old and used SFF PCs that are cheaper to buy.
"Compare now how much inflation has pushed your bills up from 10 years ago, and really the cost hasn't changed all that much."
That's not a fair comparison because the $35 price point was maintained until the Pi 4 came out in 2019 - so it's more like 5 years. And the component shortages that existed during the epidemic no longer exist, so the Pi 5 should have been a lot cheaper.
Plus food prices in the UK were mainly affected by lunatics voting for Brexit in order to make themselves poorer and impose economic sanctions on themselves just to make a few billionaires richer - we're still feeling the effects of that, but let's not go into politics here.
"I have a cheap Lonovo, and it is a great little laptop."
I have about 50 Lenovo and IBM Thinkpads. I repair and refurbish them and turn them back into usable computers with Linux.
"The end goal is to make something with a pi, in my opinion."
If that is your goal then good luck to you. But that isn't "thinking like an engineer" where you decide first what computing problem you need to solve, and then choose the hardware and software to build that solution, which also includes optimal pricing - which the Pi no longer fulfills in most cases because it is too expensive compared to using cheaper used SFF PCs. I can put Linux on anything, that's why I can "pick and choose" what I use.
"I am still working on my programming skills..."
Again, good luck to you - but you can learn programming equally well on a cheaper used SFF PC running Linux and save some money.
The external drive should have its own power.
I’m using the cable Seagate provided. I have used it for many years with all sorts of devices including Pi 4. As soon as I supplied power to the nvme from gpio it worked
🙋
my desk is always a mess, sad face. cant save it.
Hey can you make a video on raspberry pi5 running modern fortnite?
It doesn’t run. GPUs is not supported
Will Fortnite run on an SBC?
ruclips.net/video/35TBWbCTuS8/видео.html
does this make the Raspberry pi compatible with external power banks then?
It already is with many, although if you plug too much in you will get power warnings. The Raspad powers it from a battery with a screen and speakers

Try power tool bateries and buck converters. Power banks are not going to give 5.1v. I use 12v 6a minimum to power overclocked Pi4s. The buck converters I use are 5a. That's just for the Pi anything extra like screen must be considered. The official screens work great without extra power. Any other screen who knows.
Less amps on the battrry and it won't run for an hour.
Does this board enable to use a Powerbank with power delivery?
I would expect it to
@@leepspvideo sounds good tried with 20v pd receiver and bug converter but didnt work so hope it works with that
@@leepspvideo sooo it arived and it works completely fine! Means finally the pi community has a reliable simple solution for powerbank usage😍
You can daisy chain up to 127 USB devices, in theroy..Just because a USB enanled device is of a certain standard does not mean that it will be able to handle the standard if pushed. I would be hard pressed to say if a modern computer could even handle the 127 device limit on the USB 2.0 standard. I remember silly little facts from my certification days. And here is me thinking will i ever use this info?
So. Daisy chain 127 devices and you could tax that pi enough to use the wattage and amps in your vidio. Would it run the 127 devices? Prolly not. I think the pi would fry before it even got close
Of course those devices could bring their own power supply and work just fine.
It’s the 1600ma limit on Pi 5 that would quickly be maxed out. I was thinking of powering HDD’s with gpio like an old ide PC
@@leepspvideo Action Retro has just done that on his channel (connect a Pi to IDE disks and boot from them) - it's interesting to see once but has zero use in the real world.
@@JeffBromley Yeah but could a raspberry pi 5 handle the information flow of 127 self powered USB devices? I dount it. Even a modern computer would stuggle under those circumstance is my guess.
Hey Man!!!, buy a mini PC, and put your mind in peace.

You can pick up used 3rd or 4th generation Core i5 and i7 SFF PCs on "your favourite auction site" for the half the cost of a Pi 5 (by the time you've added in case, cooling and PSU) - plus you stop a bit of landfill instead of creating more of it buying those cheap rubbish Chinese mini PCs.
Do you ever think about the issue that the circuit board of Pi 5 cannot receive such high 8A current and could be burnt down? Pleas go USB-IF and check the USB-C PD compliance, and you will find that the USB-C socket only can receive a maximum current of 5A, so this power converter board inputting 5V 8A through the USB-C socket on the Pi 5 could burn it down!!!
The Pi 5 doesn't receive 8 amps. If you look at the spec sheet, the output to pi is 5A. The board has additional outputs that can draw that extra power.
