WiFi Module - ESP8266

Description: The ESP8266 WiFi Module is a self-contained SoC with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. With the ESP8266 you will be able to either host an application or offload all Wi-Fi networking functions from another application processor.

The module comes pre-programmed with an AT command set firmware. That means you can just hook this up to your Arduino device and get about as much WiFi-ability as a WiFi Shield offers! The ESP8266 is an extremely cost effective board with a huge, and ever growing, community.

The ESP8266 has a powerful enough on-board processing and storage capability that allows it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, including the front-end module, is designed to occupy minimal PCB area. The ESP8266 supports APSD for VoIP applications and Bluetooth co-existance interfaces, it contains a self-calibrated RF allowing it to work under all operating conditions, and requires no external RF parts.

There is an almost limitless fountain of information available for the ESP8266, all of which has been provided by amazing community support. In the References section below you will find many resources to aid you in using the ESP8266, even instructions on how to transform this module into an IoT solution! Also, be sure to check the SparkFun ESP8266 Thing, which is essentially a breakout and development board for the ESP8266 WiFi Module.

Note: The ESP8266 Module is not capable of 5-3V logic shifting and will require an external Logic Level Converter. Please do not power it directly from your 5V dev board.

Note: This new version of the ESP8266 WiFi Module has increased the flash disk size from 512k to 1MB.
