Iduino Yun cloud
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.
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.
