Wireless is wonderful, although the WiFi/LoRa solutions get cheaper these days, but sometimes you want the strong reliability of wire, that is why this Maduino zero Ethernet.
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.
This Maduino Zero Ethernet lets you add quick and easy wired Internet. Just plug in a standard Ethernet cable, 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.
