HW dev kit supports smart IoT devices
The hardware development kit (HDK), based on the MediaTek MT7687F Wi-Fi system-on-chip (SoC), supports developers looking to create advanced connected appliances, home and office automation devices, smart gadgets and other IoT innovations. Future HDKs will enable developers to target other IoT device segments with comprehensive wireless technology options, including Bluetooth and cellular connectivity.
The platform is based on the popular FreeRTOS with modules (source code available) for TCP/IP, SSL/TLS, HTTP (client and server), SNTP, DHCP daemon, MQTT, XML and JSON. It supports SoCs based on the ARM Cortex-M4 architecture, offering high performance, low power connectivity, and boasts comprehensive support for peripheral interfaces; such as UART, I2C, SPI, I2S, PWM, IrDA and ADC.
Other key features include: chipset specific features support, such as Wi-Fi using the MT7687F, and development and debugging support in Keil μVision and with command-line tools.
The LinkIt 7687 HDK is developed by Silicon Application Corporation (SAC), using hardware board reference design from MediaTek. The HDK provides a low-cost, easy-to-use IoT development board for the design, prototyping, evaluation and implementation of commercial IoT projects. The board offers developers a range of essential features to ensure devices are market ready. Key features of the SoC and board include:
- MT7687F module on board – the same module is available for manufacture of final IoT products;
- Wi-Fi with integrated security engine (AES and 3DES/SHA);
- Embedded SRAM/ROM and 2MB serial flash;
- Battery (2xAA) and fixed power connection options;
- Support for essential pre-commercial testing from a debugging port, a U.FL connector and headers reserved for power consumption monitoring;
- Pinout compatible with Arduino Uno (Revision 3), with an eight-pin extension connector offering versatile peripheral connectivity, including UART, I2C, SPI, I2S, PWM, IrDA and auxiliary ADC.
