The Arduino Yún is a microcontroller board based on the ATmega32u4 and the Atheros AR9331. Use this tag for questions specifically regarding the Yún, and not just general Arduino usage.

The Arduino Yún is a microcontroller board based on the ATmega32u4 and the Atheros AR9331. The Atheros processor supports a Linux distribution based on OpenWrt named Linino. The board has built-in Ethernet and Wi-Fi 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.

(From https://arduino.cc/en/Main/ArduinoBoardYun)

The main differences between the Yún and other Arduinos is that the Yún contains an onboard Wi-Fi antenna used to program the board wirelessly, connect to the Internet in sketches, or see various information about the board. The Yún also contains a Linux side, which is different because most boards only have one onboard processor. The Yún has two onboard processors; one for the system and one for the Linux part. One can connect to the Linux side of the Yún via a Bridge library. Python 2.7 is also included with the Yún.

Consider using other related tags such as or more specific to your problem.

How can I get a unique ID for all my Arduino boards?

Once you have uploaded a sketch to one of your Arduino boards, it is hard to know exactly what source code led to that sketch. Indeed, you may change the source code of your sketch on your PC without updating it (in binary format) to your board. I…
