Wireless is wonderful, but sometimes you need the strong reliability of a wired connection. The Ethernet FeatherWing adds quick and easy wired Internet to any Feather board — just plug in a standard Ethernet cable and you're connected.

Built around the WIZ5500 Ethernet controller, this FeatherWing communicates over SPI plus a single CS pin, making it compatible with all Feather boards. The Arduino Ethernet2 library handles DHCP setup automatically within seconds of connecting. The RJ-45 jack includes both link and activity LEDs to show your current connection status at a glance.
