Spektrum Dashboard is a real-time, online dashboard for monitoring and controlling your car’s speed, motor, and other vehicle data. This app also includes a built-in driver’s dashboard for monitoring important vehicle data such as motor temperature, engine temperature, battery voltage, etc.

How does it work?

Upon pairing with the installed Spektrum Bluetooth module, the application will download a firmware file from the module. This file contains the necessary software to communicate with the module. The module will then display the data on the dashboard and allow the driver to view and control the car’s speed, motor, and other vehicle data.
