The Linklt Smart 7688 development platform offers two developments boards:
LinkIt Smart 7688 is an open development board which is based on OpenWrt Linux distribution and MT7688. The board is designed especially to enable the prototyping of Rich IoT Application 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 in 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 and register here to download the SDK, participate in the Forums, and more.
