Guide to the Arduino Yún

The Arduino Yún is an Arduino board unlike any other. While programming it is very similar to

the Arduino Leonardo and uses the same processor, the Atmel ATmega32U4, it also has an

additional processor, an Atheros AR9331, running Linux and the OpenWrt wireless stack.

Programming the 32U4 via USB is identical to the Arduino Leonardo. Once you've configured

the Yún to connect to your WiFi network, you can program the 32U4 via WiFi as well.

To connect the Arduino Yún to your computer, you'll need a Micro-B USB cable. This USB

cable provides power and data to the board. When programming the Yún, you must choose

Arduino Yún from the Tools > Board menu in the Arduino IDE. The Yún is only supported

by Arduino IDE 1.5.4 and later.
