At the annual Maker Faire Bay Area, Massimo Banzi announced the Arduino Yún. The Arduino Yún (which means “cloud” in Chinese), is the first in a new family of WiFi boards combining Arduino and Linux.
The Arduino Yún is based on the existing Leonardo (an ATmega32U4) , extended with a WiFI “system-on-a-chip” (Atheros AR9331) running a modified version of the OpenWRT Linux distribution – Linino. Similarly to the Leonardo, the Yún has 14 digital I/O pins (7 PWM and 12 analog inputs) and a micro USB connector. The Arduino Yún features Wi-Fi and a standard USB socket for connecting to external USB devices. It also features a micro-SD card slot for additional storage.
WiFi and Arduino-Linux Communication
The Arduino Yún can connect to your computer, and network, wirelessly. Simply turn on the Yún, and it will create an WiFi network and access point named “Arduino”. You can then connect to the board to your network by using your internet browser to configure the settings. The Bridge library is incorporated into your sketches, an links the ATmega and Linux chips together, allowing you to pass variables such a sensor data between the chips.
The Arduino Yún will be available at the end of June for $69+tax.
UPDATE: The Arduino Yún is available now.
