Hardware Development Kit
The LinkIt Smart 7688 hardware development kit (HDK) delivers two development boards: LinkIt
Smart 7688 (offering an MPU alone) and LinkIt Smart 7688 Duo (offering an MPU and MCU). The
MPU is powered by MediaTek’s MT7688AN SOC and the MCU is powered by an ATmega32U4.
The MPU supports the OpenWrt Linux distribution; it processes an application’s intensive logic
tasks and provides Wi-Fi connectivity. It supports Python, Node.js and C programming languages.
The MCU handles real-time peripheral control as well as offering the ability to run Arduino
sketches.
