Makerfabs Maduino Zero Ethernet

The Maduino Zero Ethernet lets you add quick and easy wired Internet. Just plug in a standard Ethernet cable, and the WIZ5500 chip communicates over SPI plus a single CS pin to the Maduino zero controller ATSAMD21G18. 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.
