3DoT Board



3Dot v12

With all the hardware and software required to operate a robot on a single 35x70mm printed circuit board; the 3DoT is the brain, power, and the controller of your robot.

The board works out-of-the-box using the included app, allowing you to bring your robot to life instantly.

OR, you can program the board yourself, using your programming language of choice, such as the easy-to-use Arduino IDE!

Arduino IDE compatible robot code

Turn your robot into a telepresent robot by connecting to your phone through the Control Panel
