LinkIt One

The LinkIt One combines a MediaTek SoC, GSM, Bluetooth, WiFi, GPS, audio, and more onto a single, Arduino-style board.

Specifications Top

Designed for IoT applications and wearable electronics, the LinkIt One combines numerous technologies into one convenient (and well connected) package. MediaTek's MT2502A ARM7 SoC processor works seamlessly with the WiFi and GPS chipsets to ensure usability and reduce power consumption. The onboard GSM / GPRS modem provides ubiquitous connectivity (SIM card not included) for web / cloud enabled applications. Bluetooth 2.0 and 4.0 are also supported for additional connections.

The LinkIt One features an Arduino-style pinout for shield compatibility and Grove connectors for plugging into the ever-growing ecosystem of Grove products. The LinkIt One SDK integrates into the Arduino IDE to make programming the board as easy as programming an Arduino.
