power over ethernet

Review of Raspberry Pi's PoE+ HAT (June 2021)

The PoE+ HAT powers a Raspberry Pi 3 B+ or 4 model B over a single Ethernet cable, allowing you to skip the USB-C power adapter, assuming you have a PoE capable switch or injector.

Unfortunately, I can't recommend this new PoE+ HAT for most users, at least not in its current state.

For more background on PoE in general, and a bit more detail about the board itself and my tests, please watch my video on the PoE+ HAT—otherwise scroll past it and read on for all the testing results:
