ESP8266 WiFi SOC

The ESP8266 is a system on chip with an integrated WiFi Radio that has gained a lot of interest from the open source maker and hacker community as at around £3 for a development board with the ESP8266 module and a USB interface for programming and serial communication it is an extremely cheap option. There is also plenty of support from the open source community even if the documentation form the manufacturer is a little more sparse.

Here I use a Node MCU 1.0 (ESP-12E) module, purchased from AliExpress this board uses the SiLabs CP2102
