Power supply problem with C-PIO64 card
Good evening everyone, I am having power supply difficulties when I use the Raspberry Pi pair + the C-PIO64 board that you probably know. When the power supply is direct to the Raspberry, no problem. When, with the same power supply (5v - 4A), I go through the C-PIO64 board, I have the power supply problem symbol, and the red diode flashing (sometimes), or even off. If I enter the menu of BCM64 (F12), the problem disappears! I tried everything: another power supply, another 40pins cable, the problem persists. The designer of the CPIO64 card tells me that the problem seems impossible to him, because his card does not consume anything ... But in this case, what is wrong? Thank you for your advice ...
There's no way his card doesn't consume power. There's an Arduino onboard. What you're describing is the same thing that happens to the 'official' board, for the same reason - a combination of vampire power use and a smaller rail to bridge the power across to the Pi.

I have the same exact issue, Marc91360 did you deal with the problem? Do you have a solution?
Yes !
The problem was the USB A/B power cable. You need a high quality one - I use a PAXO from Amazon, and it works fine.
