ESP8266
Getting the hardware to run
This page is about athe adventure of oredering a set of 5 ESP-03 modules housing the increasingly popular ESP8266 module. and at $3 a piece, free shipping and no customs involved.... What could go wrong no?
The modules came nicely packed in a folded piece of paperbubble wrapped and individually packed in anti-static bags.
I used the following discussion to get my module set up.
http://www.esp8266.com/viewtopic.php?f=13&t=475
i actually went straight for the cloud of resistors recommended by this post.

Some things i have noticed already:
- I get some gibberish when i reset the module (probably data at a higher baud-rate) before it starts talking on 9600.
This could also be the bootloader.
- This module is running a later version (0018000902-AI03 vs 00160901) of the AT firmware than the one in the documentation that i followed.
