LinkIt Smart 7688

The Linklt Smart 7688 development platform offers two developments boards:

Linklt Smart 7688: MPU only. Powered by Media Tek MT7688.
Linklt Smart 7688 Duo: MPU and MCU. Powered by Media Tek MT7688 and ATmega 32U4.

The LinkIt Smart 7688 is an open development board, based on the OpenWrt Linux distribution and MT7688. The board is designed especially to enable the prototyping of Rich Application IoT devices for Smart Home. The board offers you the memory and packet storage to enable robust video processing. The platform also offers options to create device applications such as Python, Node.js and C programming language.

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