49 Euros Arduino Yún Rev.2 Unveiled with a Lower Profile, USB and Power Improvements

Arduino Yún board launched in 2013 was the first official Arduino combining Arduino  and Linux thanks to respectively an  Atmel ATMega32u4 microcontroller, and Atheros AR9331 MIPS WiFi SoC running Linino, a fork of OpenWrt maintained by Arduino. The company has now launched an upgraded version – simply called Arduino Yún Rev.2 – in order to to improve security, support, and open-sourceness of the board. Arduino Yun Rev.2 key specifications have actually not changed: MCU – Microchip ATMega32U4 @ 16 MHz (as used in Leonardo board) with 2.5KB SRAM, 32KB flash, 1KB EEPROM SoC – Atheros AR9331 MIPS-based Wi-Fi SoC coupled with 64MB external DDR2 and 16MB SPI NOR flash Storage – microSD card slot USB – micro USB connector + full USB 2.0 host port Connectivity – Ethernet + Wi-Fi I/Os 20 digital input/output pins (including 7x PWM outputs) 12x analog inputs But the hardware design – this time development with Seeed Studio – brings  a better and, more robust …

$69 Linux Powered Arduino Yún Board is Designed for the Cloud

Massimo Banzi announced the Arduino Yún, the first of a  family of Wi-Fi products combining Arduino with Linux, at the Maker Faire Bay Area. The company used the name Yún (云), meaning “cloud” in Chinese, as the purpose of this board to allow connection to web services directly from Arduino. Arduino Yun Specifications: MCU – Atmel ATMega32u4 @ 16 MHz (same as the one used in Leonardo board) with 2.5KB SRAM and 32KB flash SoC – Atheros AR9331 MIPS-based Wi-Fi SoC running Linino, Arduino’s own Linux distribution based on OpenWRT. It’s the same chipset as in TP-Link WR703N router. Storage – microSD card slot USB – micro USB connector + full USB host port Connectivity – Ethernet + Wi-Fi 14 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs) Arduino Yún ATMega32u4 can be programmed as a standard Arduino board by plugging it to your computer with the micro USB connector, or via …
