What is LinkIt ONE

The LinkIt ONE development board is an open source, high-performance board for prototyping Wearables and IoT devices. It's based on the world's leading SoC for Wearables, MediaTek Aster (MT2502) combined with high-performance Wi-Fi (MT5931) and GPS (MT3332) chipsets to provide you with access to all the features of MediaTek LinkIt. It also provides similar pin-out features to Arduino boards, making it easy for you to connect to various sensors, peripherals, and Arduino shields.

Schematic Diagram

LinkIt ONE is built to offer similar pin-out to the popular Arduino boards ,4-pin grove interfaces and peripheral interfaces, making it easy to add sensors, peripherals, and Arduino Shields to LinkIt ONE and create fully featured wearable and IoT device prototypes. Here you can reach some widgets to have a comprehensive understanding of this platform, and we will develop more one after another.
