Power over Ethernet (PoE) can make your project wiring a breeze - instead of needing a wire for power and data, you can use one Ethernet cable for both! All you need is this handy PoE module, and access to the center-taps on your Ethernet-capable board. Attach the four input wires, and get regulated 5V 1.8A on the other side. Amazing! https://elecena.pl/product/17502003/5v-1-8a-isolated-output-poe-module-for-raspberry-pi-3-b-or-4 2021-04-07 https://elecena.pl/product/17502003/5v-1-8a-isolated-output-poe-module-for-raspberry-pi-3-b-or-4 2021-06-08
