Wee Serial WIFI Module

Overview

Wee is a WIFI module based on ESP8266 SoC. ESP8266 comes out of nowhere and has been taking by storm the IoT world. You can find many hacking projects about it on the internet. 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 Bee 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 your projects.
