While this is certainly far from the first article on how-to power your Raspberry Pi via POE (Power-Over-Ethernet), I thought I would go ahead and document my setup and the equipment I ordered to pull this off successfully.
First, lets be clear — I am using a real POE switch — so I wanted a real POE solution for the Raspberry Pi, not one of those splitter cable solutions that simply supply a fixed power voltage over the unused pairs in a CAT5/6 ethernet cable. There is nothing wrong with that type of solution … its pretty cost effective, but its not real POE per the IEEE 802.3af (POE) or IEEE 802.3at (POE+) specifications.
So to pull this off, we need a POE splitter that can provide the required 5 VDC voltage and an adapter micro USB cable to plug into the Raspberry Pi’s power port. (And a short ethernet cable which you may already have laying around the house.)

Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
