Re: PI3B+ not work when powered by GPIO pins

Super helpful post(s) Thank you. I had the same issue, and by cutting the 3v3 connection I can now at least boot (I was in the same situation with boards that worked with the 3B but not the 3B+)

I tried a new Pi with the same results, but I suspected it wasn't the Pi since if I took SDA to ground I got a "full" results - i.e. something in every address. Anyway, eventually, af...

My next step is to try a different make. I've re-wired it 100x so I don't think I have it wrong (4 wires, how w...

Re: Cannot detect any I2C devices

Thank you, I will try that, though I fear the worst as I did try powering them from the 3.3v pin before and same result, though no pull up resistor
