Summary of 3DoT Board for building robots soon launching via Crowd Supply
The 3DoT Board is a compact (35 x 70 mm) open-source hardware solution designed for hobbyist robot projects. It integrates a brain, power source, and controller onto a single board, featuring an ATmega32U4 microcontroller, an on-board battery with automatic USB charging, and dual motor drivers. The board supports direct connections for motors and servos, offers reverse polarity protection, and includes Bluetooth 5.0 for remote control via iOS/Android apps or computers in "Community Mode."
Parts used in the 3DoT Board Project:
- ATmega32U4 microcontroller
- RCR123A 650 mAh battery with protection circuit
- FCC-certified BLE 5.0 Bluetooth module
- Dual motor driver with regulated 500 mA current limit per motor
- Standard 2.0 mm JST connectors for up to 2 DC motors
- Standard male header pins for up to 2 servos
- Female 8-pin forward sensor header
- Female 16-pin top shield header
- 3-position switch (OFF/PROGRAM/RUN)
- USB connector for charging and programming
Developers, makers and hobbyists building robot projects may be interested in a new board soon to be available from Crowd Supply in the form of the 3DoT Board. Specifically built for robot projects the 3DoT Board has been created to provide your robot with brain, power, and the controller in one small board measuring just 35 x 70 mm in size.

Plug your motors and servos directly onto the board, and a smart, current-limited power circuit allows it to drive everything from the on-board battery. Then, simply plug in the USB-connector to recharge the battery and upload your programs.
“Accessories can be plugged into headers on the top (e.g. a shield with an IMU) and front of the board (e.g. a front-facing sensor array). The board comes with an Arduino library and iOS/Android app that allow for easy development, as well as some really cool features such as Community Mode.
In Community Mode, your phone is attached to the robot, and by utilizing the phone’s cameras and Bluetooth connection to the 3DoT Board, you can control your robot from a computer anywhere in the world. Everything about the 3DoT is designed with 3D-printed, laser-cut, and other homemade robots in mind, and we can’t wait to see what you will create with it!”
