# Adafruit Ethernet FeatherWing ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/034/314/medium800/feather_3201_iso_demo_01_ORIG.jpg?1469645371) 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. ![](https://cdn-learn.adafruit.com/assets/assets/000/034/315/medium800/feather_3201_kit_ORIG.jpg?1469645476) 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. ![](https://cdn-learn.adafruit.com/assets/assets/000/034/313/medium800/feather_3201_iso_demo_02_ORIG.jpg?1469645342) 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. ![](https://cdn-learn.adafruit.com/assets/assets/000/034/316/medium800/feather_3201_side_demo_01_ORIG.jpg?1469645535) - [Next Page](https://learn.adafruit.com/adafruit-wiz5500-wiznet-ethernet-featherwing/pinouts.md) ## Primary Products ### Adafruit Ethernet FeatherWing [Adafruit Ethernet FeatherWing](https://www.adafruit.com/product/3201) Wireless is wonderful, but sometimes you want the strong reliability of a wire.
