## Description

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 3 Model B+, which has the 4 wires on a header. As you can see in Adafruit's photos, [you just need some female-female jumper wires to get the Ethernet wires to the module](https://core-electronics.com.au/premium-female-female-jumper-wires-20-x-3-75mm.html), 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 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](https://raspi.tv/2018/how-much-power-does-raspberry-pi-3b-use-power-measurements).

If you don't have access to those pins, but can power your board or computer with a micro USB cable, [check out Adafruit's 5V microUSB PoE Splitter. It's bigger and more expensive but really easy to use](https://core-electronics.com.au/poe-splitter-with-microusb-plug-isolated-12w-5v-2-4-amp.html) Great for older Raspberry Pi's (not the 3 B+), Feathers, etc)

[We also have an non-isolated version of this module, when you don't need electrical separation](https://core-electronics.com.au/5v-1-5a-output-poe-module-works-with-raspberry-pi-3-b.html).
