Adafruit Ethernet FeatherWing

The Adafruit Ethernet FeatherWing adds reliable wired networking to any Feather board, using the WIZ5500 Ethernet controller with SPI connectivity and an RJ45 port with built-in link and activity indicators.

Wireless is wonderful, but sometimes you want the strong reliability of a wire. If your Feather board is going to be part of a permanent installation, this Ethernet FeatherWing will let you add quick and easy wired Internet. Just plug in a standard ethernet cable, and run the Ethernet2 library for cross-platform networking. Works with all/any of our Feather boards as an Ethernet Client (server not supported at this time)!

Ethernet is a tried-and-true networking standard. It's supported by every hub and switch, and because there's a physical connection you don't have to noodle around with SSIDs, passwords, authentication schemes or antennas. It works great with any of our Feathers, the WIZ5500 chip communicates over SPI plus a single CS pin. The Arduino Ethernet2 library works great, and within a few seconds after connecting, will do the DHCP setup for you. As a nice extra, the RJ-45 jack has both link and activity lights that will light/blink to let you know the current connection status.

This one is designed specifically for use with Feathers, if you want a breadboard friendly version for any other microcontroller check out the Wiz5500 Ethernet Breakout.

Please note this product does not have PoE support, but you can add it by the addition of a PoE splitter. We have a version that provides 5V at 2.4 Amp max into a micro USB connector  just plug in your Feather to be powered over the micro USB connection.

Each order comes with one assembled and tested FeatherWing, plus some header. You will need to solder in the header yourself but its a quick task. Check out Adafruit's tutorial for code, schematics, files and more!
