ESP8266 ESP01 - Schematic Diagram

The ESP8266 WiFi Module is a self-contained stack that can give any microcontroller access to your WiFi network. The ESP8266 is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. The ESP8266 module is an extremely cost-effective board with a huge, and ever-growing, community.

Code Walkthrough

• Use ESP8266 Arduino Core version 2.5.0-beta2 or greater
• Will NOT work on ESP8266 Arduino Core v2.4.2 !!!
