LinkIt Smart Duo MT7688AN Development Board

LinkItTM Smart 7688 Duo(a compact controller board) is an open development board based on MT7688 and ATmega32u4. The board is compatible with Arduino Yun sketches and is based on the OpenWrt Linux distribution. The board is designed especially to enable prototyping of Rich Application IoT devices for smart home or office. As it is compatible well with Arduino, you can use different features from Arduino Yun and LinkIt Smart 7688 Duo. This will help you build rich applications based on various, robust and compiled Arduino Yun sketches. The board offers you the memory and packet storage to enable robust video processing. The platform also offers options to create device applications in Python, Node.js and C programming languages.
