Iduino Yun cloud is an ideal IoT device for Internet of Things projects. It is a compatible / replacement product for Arduino Yun. It works with Arduino IDE with version higher than 1.5.4.

The Iduino Yun cloud is a microcontroller board based on the ATmega32u4 and the Atheros AR9331. The Atheros processor supports a Linux distribution based on OpenWrt named OpenWrt-Yun. The board has built-in Ethernet and WiFi support, a USB-A port, micro-SD card slot, 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and a 3 reset buttons.

The Iduino Yun cloud is similar to the Arduino Leonardo in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Yun to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.

Features

• Open source Linux (OpenWrt) onboard
• Compatible with Arduino IDE 1.5.4 or later, user can program, debug or upload sketches to the Arduino board via the Arduino IDE.
• Managed by Web GUI, SSH via LAN or WiFi
• Software upgradable via network
• Built-in web server
• Supports internet connection via LAN port, WiFi or 3G dongle.
• Supports USB flash to provide storage for Arduino projects.
• Failsafe design provides robust system.
