How to get started in for Arduino: Setup driver: Before you use mini boards, you need setup CH340g driver. Python: On Windows you need install Python 2.7.10. On Linux & MAC OSX, you don't need install it, comes preinstalled with OS. Installing Hardware package: There is two ways to install hardware package, Boards Manager or GIT Installing with Boards Manager: Starting with 1.6.4, for Arduino allows installation of third-party platform packages using Boards Manager. We have packages available for Windows, Mac OS, and Linux (32 and 64 bit). 1. Install for Arduino 1.6.7 from the for Arduino website. 2. Start for Arduino and open Preferences window. 3. Enter http://arduino.esp8266.com/stable/package_esp8266com_index.json into Additional Boards Manager URLs field. You can add multiple URLs, separating them with commas. 4. Open Tools→Board:xxx→Boards Manager and install esp8266 by ESP8266 Community (and don't forget to select your ESP8266 board from Tools > Board menu after installation). Installing with GIT (Recommend): We recommend using GIT to install Hardware package,you can always get the latest version of it. Package includes: 7 X Mini wifi wireless module
