I have a raspberry pi 3b+ with the 4 PoE connectors. How can I power the Pi with Ethernet without buying the PoE Hat? Is there a link to a schematic for the PoE hat? I need a different board on top of my Pi.
Thanks.
Use a POE splitter: I’ve used the following with excellent results. Cheaper than a POE Hat to and leaves the GPIO pins free too!:
