About: i am electronic Hobbyist. I like to make the things and also make it available to people who need it. Please visit and subscribe my youtube channel for more Embedded related videos. https://www.youtube.com/c...

LinkIt Smart 7688 Duo is an open development board based on MT7688 and ATmega32u4. Which can be programmed using arduino and can be used heavy application running parallel. Atmega controller is used for Arduino programming and for embedded linux (OpenWRT distro) MT7688 is used.
So, this boards has two cpu and they are communicate with each other with UART interface.

Step 1: OpenWRT

OpenWrt is an open source project for embedded operating system based on Linux, primarily used on embedded devices to route network traffic. The main components are Linux, util-linux, musl and BusyBox.

All components have been optimized to be small enough to fit into the limited storage and memory available in home routers.
OpenWrt can run on various types of devices, including CPE routers, residential gateways, smartphones, pocket computers.
