DESCRIPTION

LinkIt Smart 7688

The Linklt Smart 7688 development platform offers two developments boards:


What is LinkIt Smart 7688 Duo

LinkIt Smart 7688 Duo is an open development board compatible with Arduino Yún sketches, based on the OpenWrt Linux distribution, MT7688 and ATmega32u4. The board is designed especially to enable the prototyping of Rich IoT Application for smart house or office. Since it is compatible with Arduino, this allows you to use different features from Arduino Yún and LinkIt Smart 7688 Duo, which will help you build rich applications based on various, robust and compiled Arduino Yún 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 language.

LinkIt Smart 7688 duo is a co-design product by Seeed Studio and MediaTek. It brings together the parties' knowledge in open hardware and industry leading reference designs for IoT devices to create this powerful development board.

LinkIt Smart 7688 duo is fully supported on the MediaTek Labs site: check out the LinkIt section and register here to download the SDK, participate in the Forums, and more.
