商品説明
The WIZnet WIZ550io module contains a W5500 chip - it implements TCP/IP on-chip, so you just plug an Ethernet cable in one end, and SPI into the other.
Support is provided in Espruino, but you will have to use a special build of Espruino designed for it as there isn't enough space in flash to hold both CC3000 and WIZnet drivers.
