Hello,
I recently purchased a few PoE+ hats (https://www.adafruit.com/product/5058) for the Raspberry Pi. They work just fine when plugging in to a PoE switch.
However, if i try to power them with the standard USB-C cable, it makes a terrible crackling noise. In this configuration i unplugged everything from the Pi, except the USB-C cable. I tried this on 2x Pi's both with PoE+ hats, just to rule out various factors.
Any ideas here? Is it supported to power off USB-C when the PoE+ hat is installed? Is it supposed to make that terrible crackling sound?
Thanks,
Nick
