Product Description

The Arduino Yun Rev 2 from Tronixlabs Australia is a development board based on the ATmega32U4 microcontroller and Atheros AR9331 Linux Microprocessor. It’s perfect for your IoT based projects.
The AR9331 runs Linux and OpenWRT which means the Arduino Yun can connect to WiFi and Ethernet. 

Arduino Yun Rev 2 vs. Arduino Yun

The new Rev 2 board follows on from the very popular Arduino Yun board. It has a simiar configuration to the original board but a few changes to the layout fix previous problems that users experienced.
The new model features a more robust power supply. A new Ethernet connector enables use of all relevant shield board without running the risk of accidental short circuits. A horizontal USB connector offers a lower profile and there is also an improved USB hub. 
The Arduino Yun Rev 2 offers improved functionality to the previous board and is backwards compatible with the old model.

The Yún Rev. 2 is open-source hardware! You can build your own board using the following files:



The Yún Rev. 2 board allows you to connect to the internet using the onboard WiFi or Ethernet connection. Furthermore thanks to the Bridge library it able to extend the functionalities of the Microprocessor by using the computational power of the Linux processor on the shield. Using the Yún Web Panel it is also possible to configure all the shield-related features and remotely upload sketches on the board connected to the shield. 

On-board Indicators

The shield contains a number of signalling LEDs:

  • ON (green): indicates that the shield is properly powered
  • WLAN (blue): indicates a connection to a wireless network
  • WAN (red): indicates connection to ethernet
  • USB (white) : indicates system activity and/or if a USB key is mounted
