The Arduino Yún

The Arduino Yún

Today, Arduino announced a new family of wireless products that combine the Arduino architecture with Linux. The Arduino  Yún is intended to be the first member of this new line of wifi products. Arduino expects the new board to bring the power of Linux with ease of use of Arduino.

From the Arduino Press Office, “Yún means ‘cloud’ in Chinese language as the purpose of this board to make it simple to connect to complex web services directly from Arduino.”

Developed in partnership with Boston-based automation engineers Dog Hunter, it’s basically a Leonardo (ATmega32U4) with an embedded wifi Linux board on the PCB, running Linino (MIPS Linux variant) to handle all those wordy text-based formats like XML and other HTTP transactions. You can program it via wifi, or by the usual USB cable. And they’ve also partnered with Temboo for one-stop API access to data from Twitter, Facebook, Foursquare, FedEx, PayPal, and many more.

For $69 plus tax you get:
