Adafruit HUZZAH ESP8266 Breakout

Add Internet to your next project with an adorable, bite-sized WiFi microcontroller, at a price you like! The ESP8266 processor from Espressif is an 80 MHz microcontroller with a full WiFi front-end (both as client and access point) and TCP/IP stack with DNS support as well. While this chip has been very popular, its also been very difficult to use. Most of the low cost modules are not breadboard friendly, don’t have an onboard 500mA 3.3V regulator or level shifting, and aren’t CE or FCC emitter certified….UNTIL NOW!
