RS Components is now stocking Arduino Yún, the first member of a new family of wireless products that integrate the open-source Arduino architecture with Linux.
Yún, meaning ‘cloud’ in a Chinese dialect, combines the existing 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 new board is a Bridge library, which makes it easy to navigate complex Web services that use verbose, RAM-intensive text-based formats such as XML by delegating all network connections and processing of HTTP transactions to the Linux-based SoC.
In common with Arduino Leonardo, the Yún has features such as 14 digital input/output pins, seven pulse width modulation (PWM) channels and 12 analog inputs. It also incorporates a 16 MHz crystal oscillator and a micro USB connector plus a Standard-A type USB connection and a PoE compatible microSD card socket for additional storage.
Upon being powered up for the first time, the Yún functions as a Wi-Fi access point, creating a Wi-Fi network called ‘Arduino’. The board can then be configured by entering a Wi-Fi network name and password.
