Arduino Yun SBC adds Wifi and Linux to Leonardo features

[Updated Sep 30] — Arduino announced the first open source Arduino hacker board with built-in WiFi, and also the first to run Linux. The $69 Arduino Yun integrates the functions of an Arduino Leonardo, featuring an Atmel ATmega32U4 microcontroller and 14 GPIO pins, with an Atheros AR9331 WiFi SOC running OpenWRT embedded Linux on a 400MHz MIPS processor. Arduino, the Italian-based project that designs the o ...

Arduino Leonardo AVR Development Board

Arduino Leonardo AVR Development Board is a microcontroller board based on the Atmel ATmega32u4. It offers 20 digital IOs (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. The Arduino Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating ...
