Yún Rev2-board

Yún Rev2

The Yún Rev2, Linux powered board with the Arduino simplicity, is the perfect board for your IoT projects!


The Yún Rev2 has the power of a Linux based system that enables advanced network connections and applications. Connecting to your Wi-Fi or wired network is simple thanks to the Yún Web Panel and the dedicated YunFirstConfig sketch. The Web panel allows you to manage your shield preferences and upload your sketch. The Yún Rev2 uses the Bridge library and so extends the board capabilities by using the Linux processor.


The ATmega32U4 executes powerful instructions in a single clock cycle, achieving throughputs approaching 1 MIPS per MHz allowing the user to optimize power consumption versus processing speed.

Atheros AR9331

The Atheros AR9331 is a highly integrated and cost effective 2.4 GHz System-on-a-Chip (SoC) for wireless local area network (WLAN) AP and router platforms.

Internet connection

The Yún Rev2 board allows you to connect to the internet using the onboard WiFi or Ethernet connection.


First Steps

Quickstart Guide
All you need to know to get started with your new Arduino board.

Suggested Libraries

Using the Bridge library we are able to extend the functionalities of the Microprocessor by using the computational power of the Linux processor on the shield.
This library allows you to communicate with I2C / TWI devices.
The SPI library allows you to communicate with SPI devices, with the Arduino as the controller device.

Arduino Basics

Built-in Examples
Built-in Examples are sketches included in the Arduino IDE and demonstrate all basic Arduino commands.
In Foundations you can find some specific knowledge about the principles and techniques that are behind the Arduino.
Language References
Arduino programming language can be divided in three main parts: functions, values (variables and constants), and structure.
