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.
