I received my WiDos ! Three of them. They were out of stock so I had to wait a few more days after order but they eventually arrived through DHL delivery after one week of patience. I had to pay french taxes in addition the product price. Fair enough : I was warned !\"WiDo<\/a><\/p>\n

The WiDo is an Arduino Leonardo compatible board including a Wifi chip and an SD card reader. It\u00a0should be noted that some on the pins are used by either the wifi or the SD card : pins D4, D5, D7 and D10 are not available. Also, the wifi chip is using SPI top communicate with the microcontroller.<\/p>\n

The Jorjin WG1300 seems to be based on the TI CC3000 chip. So it work with the Adafruit CC3000 library<\/a>. There is also a WiDo fork<\/a> for the library but it seems there is no change to the library itself. Only examples are updated (changing IRQ pin from 3 to 7) or created (Xively…)<\/p>\n

I stuck to the the Adafruit original. I just loaded the\u00a0buildtest example, changed IRQ pin, set my Wifi SID and WPA password… and it worked like a charm !<\/p>\n

The only problem I have with one on the board is the mis-alignment of some headers.\"WiDo<\/a>It is not preventing the board to work but you can’t use shields as they won’t fit. I may try to re-solder the header.<\/p>\n

So, at around 25\u20ac, the WiDo is a great replacement for an Arduino + Wifi shield which costs around 70\u20ac ! And it works just like the Adafruit CC3000 Wifi shield.<\/p>\n

The next step is to port the Wifridge on WiDo.<\/p>\n

By the way,\u00a0official documentation is here<\/a>.<\/p>\n
