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.

The Shim available for the Espruino Pico helps to adapt the W550io to fit onto the Pico. Please see the video below:
Just wire up J1 as follows. J2 does not need wiring up.
WIZ550io J1 | Name | Espruino |
---|---|---|
1 | GND | |
2 | GND | GND |
3 | MOSI | B5 |
4 | MISO | B4 |
5 | SCK | B3 |
6 | CS | B2 |
7 | 3V3 | 3V3 |
8 | 3V3 |
On the Espruino Pico, the adaptor shim uses the following connections:
WIZ550io J1 | Name | Espruino |
---|---|---|
1 | GND | |
2 | GND | GND |
3 | MOSI | B15 |
4 | MISO | B14 |
5 | SCK | B13 |
6 | CS | B10 |
7 | 3V3 | 3V3 |
8 | 3V3 |
Just connect as follows:
var eth = require("WIZnet").connect();
Or for the Espruino Pico adaptor:
SPI2.setup({ mosi:B15, miso:B14, sck:B13 });
var eth = require("WIZnet").connect(SPI2, B10);
You can check your IP with:
eth.getIP()
The module gets its own IP, however it does not configure DNS by default (for looking up domain names). To do this either:
eth.setIP({ dns : "8.8.8.8" }); // google's DNS
Or use DHCP:
eth.setIP();
Create an HTTP server like this:
require("http").createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.write('Hello World');
res.end();
}).listen(80);
Or load a webpage like this:
require("http").get("http://192.168.1.50", function(res) {
res.on('data', function(data) { console.log(data); });
});
For more examples, please see the Internet page.
You can buy this module from:
However when buying direct from WIZnet, the cost of postage may end up being particularly high.
