Itead Wee Serial WIFI Module XBEE Form Factor

Wee is a WIFI module based on ESP8266 SoC with xbee form factor.  So far, the most popular ESP8266 breakout version only has GPIO0 and GPIO2 routed to the header. Compared to it, Wee WIFI module is designed with a standard xBee interface and has more GPIOs available for developers. In a word, users can take full use of the utility of ESP8266 SoC by using Wee WIFI module in the projects.
