Arduino Yun Rev 2

The Arduino Yun Rev 2 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.
