This is the new Raspberry Pi 3 Model B+ PoE HAT, a handy add-on board that allows you to power your Raspberry Pi 3 Model B+ by using an ethernet cable! In addition, it has a 25mm fan that provides cooling to the Pi and its CPU.
Follow our guide on how to attach the PoE HAT to the Raspberry Pi. We will show you how to connect it to the Pi and a PoE-capable network router.
Note: The HAT will only work with PoE-capable network routers or switches, standard routers or switches will not work here!
