MediaTek Labs Webinar: Getting Started with LinkIt ONE
3 likes2,125 views
This document provides an overview of the LinkIt ONE hardware development kit (HDK) and software development kit (SDK) from MediaTek Labs for developing wearable and IoT devices. The LinkIt ONE HDK features the Aster MT2502 system-on-chip and companion chips for WiFi, GPS, and more. The LinkIt ONE SDK extends the Arduino IDE with APIs for features like SMS, GPS, audio, and GPRS. It also describes MediaTek's cloud sandbox for visualizing device data and updating firmware over the air. Other discussed HDKs include the LinkIt Connect 7681 and LinkIt Assist 2502.
