Overview

MediaTek LinkIt™ ONE development platform enables you to design and prototype Wearable and Internet of Things (IoT) devices, using hardware and an API that are similar to those offered for Arduino boards.

Key features

  • All-in-One connectivity: Based on MediaTek MT2502A SoC, offering comprehensive communications and media options, with support for GSM, GPRS, Bluetooth 2.1 and 4.0, SD Cards, and MP3/AAC Audio, as well as Wi-Fi and GNSS (hardware dependent)

  • LinkIt ONE development board from partner Seeed Studio with similar pin-out to the Arduino UNO enabling a wide range of peripheral and circuits to be connected to the board

  • LinkIt ONE SDK (for Arduino) offering instant familiarity to Arduino developers and a easy to learn toolset for beginners

LinkIt™ ONE

The LinkIt ONE development kit includes a development board, a Wi-Fi and Bluetooth antenna, GSM (2G) antenna and GPS/GLONASS antenna as well as a Li-battery. Using the included quick start guide you can be up and running with your proof-of-concepts in no time.


You can then add Grove sensors or any peripherals compatible with the extensive pin and interface standards supported by the board.


Co-designed with Seeed Studio, this kit has everything you need to get started.

Key features

  • All-in-One connectivity: Supports GSM, GPRS, Wi-Fi, Bluetooth (2.1 SPP and 4.0 GATT profiles), GNSS (GPS, GLONASS and BeiDou), Audio out and SD card connectors

  • Pin-out similar to Arduino UNO, including Digital IO, Analog IO, PWM, I2C, SPI and UART

  • Open hardware board reference design including schematic, layouts and pin details
