Inside the Arduino Yún

YunParts

 

The Arduino Yún is the newest member to the Arduino line up and is in a class all its own.  The Overview from Arduino.com…

The Arduino Yún is a microcontroller board based on the ATmega32u4 (datasheet) and the AtherosAR9331. The Atheros processor supports a Linux distribution based on OpenWRT named Linino. The board has built-in Ethernet and WiFi support, a USB-A port, micro-SD card slot, 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and a 3 reset buttons.

The Yún distinguishes itself from other microcontrollers with its ability to communicate with the Linux distribution onboard. This feature allows users to easily interact with their Yún using Python script and shell in onboard.  Below are more detailed specs on the Arduino Yún.
