Arduino Yún wireless board

The Arduino Yún is the first of a range of wireless products that integrate the open-source Arduino architecture with Linux. The product combines the Arduino Leonardo, based on Atmel’s ATmega32u4 8-bit microcontroller, with an embedded Atheros AR9331 Wi-Fi system-on-chip (SoC) running Linino, a MIPS GNU/Linux variant of OpenWRT.

The principal feature of the board is a Bridge library, which makes it easy to navigate complex web services that use RAM-intensive, text-based formats such as XML by delegating all network connections and processing of HTTP transactions to the Linux-based SoC. Other features include 14 digital input/output pins, seven pulse width modulation (PWM) channels and 12 analog inputs.

It incorporates a 16 MHz crystal oscillator and a microUSB connector plus a Standard-A type USB connection and a PoE compatible microSD card socket for additional storage. Once the device is powered up for the first time it functions as a Wi-Fi access point, creating a Wi-Fi network. The board can then be configured by entering a Wi-Fi network name and password.

The product is suitable for anyone wishing to develop interactive objects and environments. It is said to make possible a host of open-source design opportunities and applications that were previously out of reach using existing Arduino boards.
