A new hardware Development Kit from MediaTek supporting IoT devices, was announced on Tuesday. MediaTek LinkIt™ Development Platform for RTOS, is a first from MediaTek, delivering a common tool chain, and sets of APIs for multiple chipsets. This offers developers, the ability to create a range of IoT devices from a common MediaTek LinkIt SDK v3.

With support for creating advanced connected home appliances, home and office automation devices, smart gadgets and other IoT innovations, the HDK is based on the MediaTek MT 7687F Wi-Fi SoC. Support for Bluetooth and cellular connectivity is expected in the future releases, for the developers to target other IoT segments.

“Professional developers continue to be catalysts for turning IoT ideas into actual products. MediaTek Labs is committed to delivering the best hardware and software development platforms, as well as technical and business matchmaking support, for these developers to quickly get to market,” said Marc Naddell, Vice President of MediaTek Labs. “The MediaTek LinkIt™ Development Platform for RTOS opens the door for developers to build a full range of IoT devices that are power efficient with secure Wi-Fi connectivity and commercially viable.”

Features of the new RTOS Development Platform:

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.
Supports SoCs based on the ARM Cortex-M4 architecture, offering high performance, low power connectivity.
Comprehensive support for peripheral interfaces; such as UART, I2C, SPI, I2S, PWM, IrDA and ADC.
Chipset specific features support, such as Wi-Fi using the MT7687F.
Development and debugging support in Keil μVision and with command-line tools.
Silicon Application Corp.(SAC) developed the LinkIt 7687 HDK using MediaTek board for reference design. With features for designing, prototyping, evaluation and implementation of commercial IoT projects, this seems to be a low cost easy to use IoT development Board.

Key features of the SoC and Board are listed as:

MT7687F on board module. It is also 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.
