The Arduino Yún is a microcontroller board based on the ATmega32u4 and the Atheros AR9331. The Atheros processor supports the 'Linino' Linux distribution, which is based on OpenWRT. The board has built-in Ethernet and WiFi support, a USB-A port, a micro-SD card slot, 20 digital I/O 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 3 reset buttons.

The Yún distinguishes itself from other Arduino boards in that it can communicate with the onboard Linux distribution, offering a powerful networked computer combined with the ease of use of Arduino. In addition to using Linux commands like cURL, you can write your own shell and python scripts for robust interactions.

The Yún is similar to the Leonardo. The ATmega32u4 supports USB communication in hardware, eliminating the need for a secondary processor. When connected to a computer, this allows the Yún to appear as a mouse and keyboard, in addition to a virtual (CDC) serial/COM port.

The Bridge library facilitates communication between the two processors, offering Arduino sketches the ability to run shell scripts, communicate with network interfaces, and receive information from the AR9331 processor. The USB host, network interfaces and SD card are hard-wired to the AR9331, not to the ATmega32u4. The Bridge library enables the Arduino to interface with those peripherals.


Because the Yún has two processors, the summary section shows the characteristics of each one in two separate tables.

AVR Arduino microcontroller:
Microcontroller ATmega32u4
Operating Voltage 5V
Input Voltage 5V
Digital I/O Pins 20
PWM Channels 7
Analog Input Channels 12
DC Current per I/O Pin 40 mA
DC Current for 3.3V Pin 50 mA
Flash Memory 32 KB (of which 4 KB used by bootloader)
Clock Speed 16 MHz
Linux microprocessor:
Processor Atheros AR9331
Architecture MIPS @400MHz
Operating Voltage 3.3V
Ethernet IEEE 802.3 10/100Mbit/s
WiFi IEEE 802.11b/g/n
USB Type-A 2.0 Host/Device
Card Reader Micro-SD only
Flash Memory 16 MB
PoE compatible 802.3af card support  



It is recommended to power the board via the micro-USB connection with 5VDC. If you are powering the board through the Vin pin, you must supply a regulated 5VDC. There is no on-board voltage regulator, so higher voltages will damage the board.

The Yún is also compatible with PoE power supply, but in order to use this feature, you need to mount a PoE module on the board or buy a preassembled one.
