Arduino Yún Rev 2 Board

Arduino Yún Rev 2 Board: connect to your WiFi or Ethernet network

The new version of this Arduino board features the same great characteristics as its predecessor: it combines an ATmega32U4 microcontroller (Leonardo-like) and a Linux processor with WiFi and Ethernet support. This means that you can develop all your Internet of Things projects in an Arduino environment, with the power of a Linux on-board computer. The two processors can communicate thanks to an Arduino code library.

You’ll get some added benefits:

• A more robust and powerful supply;
• A new Ethernet connector;
• A wider range of applications thanks to a smart assembly solution;
• A software stack including the latest OpenWRT update.
