How to Install the ESP8266 Board in Arduino IDE

http://randomnerdtutorials.com/how-to-install-esp8266-board-arduino-ide/

Features:
D1 mini, it is a mini NodeMcu Lua WiFi board based on ESP-8266EX.
11 digital input/output pins, all pins have interrupt/pwm/I2C/one-wire.
ESP8266 has I/O Pin.
No need to download restting.
A great set of tools to develop ESP8266.

Specifications:
supported(except D0)
1 analog input(3.3V max input)
A Micro USB connection
Dimension:

How to get started in Arduino:

Setup driver:
Before you use miniD1 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, 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 Arduino 1.6.7 from the Arduino website.
2.Start 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:
1x Mini NodeMCU Lua Wifi Wireless Module
2×Long female pins
2×Short female pins
2×Normal pins
