LinkIt Smart 7688 - a more connected world
1 like•1,349 views
The document discusses the LinkIt Smart 7688 development board. It has an MT7688 system on chip with WiFi, 32MB flash, and supports 18 servo motors. It can be programmed via OpenWRT using C/C++, Python, or Node.js. The board works with the MRAA and UPM libraries to control sensors and I/O. It also describes the MediaTek Cloud Sandbox, a cloud platform for prototyping and collecting data from IoT devices.
