WIZnet WIZ550io/W5500 Ethernet module

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.

For the WIZnet W5100, see this page

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.

To get the latest WIZnet binary:

• Go to http://www.espruino.com/binaries and look for a file titled espruino_XXX_espruino_1r3_wiznet.bin, where XXX is the latest version

• Click on Flasher
• Paste the link into the Advanced Firmware Update text box
