Arduino Yún

Image
The Arduino Yún is a microcontroller board based on the ATmega32u4 and the Atheros AR9331.
You can find the ATmega32u4 datasheet here .
The Atheros processor supports a Linux distribution based on OpenWrt named Linino OS. 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 3 reset buttons.

How to use your board

Note

In some countries, it is prohibited to sell WiFi enabled devices without government approval. While waiting for proper certification, some local distributors are disabling WiFi functionality. Check with your dealer before purchasing a Yún if you believe you may live in such a country.
If you need to disable WiFi, run this sketch

Schematic & Reference Design

Since Arduino is an open-source electronics platform, here we provide the Board schematics and the Reference design

  • Ciao - a easy-to-use and powerful technology that simplifies interaction between microcontroller and the "outside World".
  • Bridge - Handles communication between the Linux processor and the Arduino on the Yún.
  • Keyboard - Send keystrokes to an attached computer.
  • Mouse - Control cursor movement on a connected computer.
