Adafruit WiFi / 802.11 Development Tools Huzzah ESP8266 Breakout

Key Features: Difficult to use ESP8266 chip(80 MHz microcontroller with a full WiFi front-end) has been updated with PCB + extras Designed to make working with ESP8266 processor super easy and a lot of fun Has an "FTDI" pinout to plug in an FTDI or console cable and upload software and read/write debugging information via the UART. Pre-loaded with NodeMCU's Lua interpreter (NodeMCU 0.9.5 build 20150318 / Lua 5.1.4) Add Internet to your next project with an adorable, bite-sized WiFi microcontroller, at a price you like! The popular ESP8266 processor from Espressif with TCP/IP stack with DNS support has 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!The Adafruit HUZZAH ESP8266 breakout was designed to make working with this chip super easy and a lot of fun. We took a certified module with an onboard antenna, and plenty of pins, and solde
