After presenting WeIO, here is WiDo from DFRobot, yet another Open Source IoT node.

It is basically an Arduino Leonardo which includes a WG1300 WiFi chip. Apparently, this can be used with Adafruit’s CC3000 Arduino library which should make it quite straightforward to use.

What’s the difference between an Arduino + a CC3000 shield then ? The price ! At less that $30, it makes a quite cheap IoT plateform !

Ordered some… (DHL shipping is free until the end of september) but no more in stock. So I don’t know when I will receive them 🙁
