ARDUINO YÚN REV 2 with the power of a Linux-based system enables advanced network connections and applications. Connecting to your WiFi or wired network is easy thanks to the Yún web panel and the dedicated "YunFirstConfig" sketch. The web panel allows you to manage your board preferences and upload your sketch. ARDUINO YÚN REV 2 uses the Bridge library and thus extends the capabilities of the board using the Linux processor.
As always, every element of the platform - hardware, software, and documentation - is freely available and open-source. That means you can learn exactly how it's made and use its design as a starting point for your own projects.
