$5 wifi module ESP8266
Some email chatter today among the Aussie forum members about this new module. All very new, not sure if anyone has one yet, several on order and on the way.
Hackaday have covered it http://hackaday.com/2014/08/26/new-chip-alert-the-esp8266-wifi-module-its-5/
More specs here https://nurdspace.nl/ESP8266
Hardware looks like SPI. Software is a work in progress - it seems people are writing code before even getting hold of the module.
I've got one on order (search ESP8266 on ebay). Possible to interface with a Propeller? Or impossible...
