Arduino Yun Rev 2 (Original Arduino-Italy)



The Yún Rev 2, Linux powered board with the Arduino simplicity, is the perfect board for your IoT projects!

The Yún rev. 2 with the power of a Linux based system that enables advanced network connections and applications. Connection to your WiFi or wired network is simple thanks to the Yún Web Panel and the dedicated ”YunFirstConfig” sketch. The Web panel allows you to manage your shield preferences and upload your sketch. The Yún rev. 2 uses the Bridge library and so extends the board capabilities by using the Linux processor.

Arduino Yún Rev 2 is a Microcontroller Board based on the Microchip Technology ATmega32U4 8-bit Microcontroller and the Qualcomm Atheros AR9331 Processor. The Atheros Processor supports a Linux distribution based on OpenWrt named LininoOS. The board has built-in 802.3 10/100Mbit/s Ethernet and Wi-Fi® 802.11b/g/n 2.4GHz, making it ideal for connected IoT (Internet of Things) applications. Connection to a Wi-Fi or wired network is simple thanks to the YÚN Web Panel and the dedicated ”YunFirstConfig” sketch. Using the Yún Web Panel it is also possible to configure all the shield-related features and remotely upload sketches on the board connected to the shield. The Yún Rev 2 uses the Bridge library, extending the functionalities of the Microprocessor by using the computational power of the Linux processor on the board.

The Yún Rev 2 offers a space saving hoizontal Micro USB port and full USB 2.0 host, and a low-profile Ethernet 10/100 RJ45 port, designed to avoid potential short circuits when used with shields. Additional features include a microSD card slot, 20 digital input/output pins (7 of which can be used as PWM outputs and 12 as analog inputs), a 16MHz crystal oscillator, an ICSP header, 4 on-board status LEDs, and 3 reset buttons.

As always, every element of the platform – hardware, software and documentation – is freely available and open-source. This means that developers can learn exactly how it’s made and use its design as the starting point for your own projects.

Note: This is 100% Original ARDUINO board.
