Adafruit 5V 1.8A Isolated Output PoE Module for Raspberry Pi 3 B+ or 4

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!

This version of the PoE module has a transformer in the center, that's the big chunky thing, so that there is no direct electrical connection between the 5V power/ground and Ethernet cables.

This module works well with the Raspberry Pi 4 or Pi 3 Model B+, which has the 4 wires on a header. As you can see in our photos, you just need some female-female jumper wires to get the Ethernet wires to the module, and then two wires to bring the 5V back to the header. Note that even though a 2.5A power supply is recommended for a Pi 4 / 3B+, that's only required if you attach a bunch of accessories (such as a 7" display!) 1.8A will cover a wide range of usages, as the current draw is around 0.7A max without extras.

We also have an non-isolated version of this module, when you don't need electrical separation.
