No matter whether it's on Raspberry 3 or older HW version (red PCB, you know...). I was trying different Raspberries, different microUSB cables with no result. I guess there's something wrong with AUC2 itself? Can I somehow fix it?
I have another 2 AUC2s with no LEDs shining, I guess there will be harder (or impossible) to fix those two... But I need this one which is shining!..
