Power over Ethernet (PoE) expansion board can make your project wiring a breeze - and best of all they work to connect any 802.3at/802.3af-capable router  to your Raspberry Pi 3 model B+ and 4 model B.  You can now power your Raspberry Pi and other devices in any location with just a single cable. Perfect for removing the clutter of wires and for reliable use in remote locations.

This is an economical, practical, high-performance, and reliable Isolated 5V 5000mA PoE+ expansion baord with a variety of power output connectors based on IEEE 802.3at standard. It can divide power from a network cable, and can be used with any PoE/POE+ injector that is compatible with IEEE 802.3at /802.3af, and supply power for Raspberry Pi and other non-PoE network equipment.

Simply attach the standoffs in the four fixed holes of the expansion board, then connect to the Raspberry Pi's pin header using the specially-made daughter board. Once the board is connected, you can power your Pi through the RJ-45 network connector.

The X765 board is directly connected on top of the Raspberry Pi using the board GPIO header pins, and no wiring nor soldering is required, and duplicated the 40-pin header of the R-Pi in order to support existing expansion boards. X765 is fully compatible with Raspberry Pi 3B+ and Pi 4 B.
