ESP8266 Wi-Fi Module

Add Wi-fi and web capabilities to your project with this module which is currently in rapid development.
The module operates at 3.3V, so level shifting may be required.
We have used the PL2303HX USB to TTL serial adaptor (M029), which operates at 3.3V, to carry out firmware upgrade and AT command communications tests with our first samples.
Note: The module needs a 3.3V supply capable of supplying bursts of current up to around 350mA. Do not use the output from an Arduino - it just isn't up to the job.
