“If you're using a Raspberry Pi 3B+ (or 4) and want to cut down on cables, the PoE HAT is a super handy add-on. It lets you power your Pi through the Ethernet cable, so you don’t need a separate power supply, just plug it into a PoE switch or injector and you’re good to go.
For anyone setting up a Pi as a server, in a remote spot, or just wants a cleaner setup, this thing makes life a lot easier.”
“An excellent compact way to add PoE to your Pi 3/4. I needed to remove the mounting hole parts from the corners to allow it to fit in the FLIRC Pi3 case I have, not ideal but simple enough to do. If you need PoE for your project this is a simple cost effective way to go.”
“This worked just as I wanted, no configuration in the OS required, just plugged in the PoE cable from my PoE Switch and the Pi powered straight up. It does have a small capacitor/winding on it which means that standard fans inside cases probably won't fit. I used an open case, added a heatsink to the cpu and moved the fan to the top of the case. It runs at”
