LinkIt A-Core Packs Mediatek MT2502A SoC into a Tiny Module for Wearables

LinkIt ONE is a development board based on Meditak MT2502A SoC for wearables, and developed by SeeedStudio. With GPS, Wi-Fi, and GSM/GPRS connectivity, and a LiPo battery, it’s great to experiment IoT or wearable applications, but if you plan to launch an actual product, it could be nice to have a module, and built a baseboard around it. That’s exactly what SeeedStudio is working with LinkIt A-Core module.
