General Description


The EK-AI7688H KIT board provides an affordable way for user to try out WiFi Access point in IoT applications or new concepts evaluation. The development board uses MT7688AN as a standalone MPU and supports application development in Python, Node.js and native C programming languages. 

User can download SDK from AcSiP FTP site to develop software applications based on OpenWrt which is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application.
