To enable developers to leverage the features of the MT7681 SoC, the new platform offers a software development kit (SDK) for Microsoft Windows and Ubuntu Linux, a hardware development kit (HDK) co-designed with Seeed Studio, and related documentation. The SDK allows developers to collect and upload the firmware needed to control an IoT device in response to wirelessly received instructions, while the HDK provides the LinkIt Connect 7681 development board. The board includes the LinkIt Connect 7681 module, a micro-USB port, and pins for each of the MT7681 chipset's I/O interfaces. The LinkIt Connect 7681 module (co-designed with AcSiP) is available for separate order and is designed for easy PCB mounting as part of the IoT device's product releases.
Connectivity in the MT7681 is achieved using Wi-Fi, in either Wi-Fi station or access point (AP) mode. In Wi-Fi station mode, the MT7681 connects to a wireless access point and can communicate with web services or cloud servers, enabling uses such as controlling home heating from a home automation website. In AP mode, the MT7681 chip allows other wireless devices to connect directly to it, enabling, for example, a smartphone app to control a smart plug or light bulb in the home.
