Assembled Actobotics® Dual Motor Controller


The Actobotics® Dual Motor Controller provides a compact solution for controlling 2 brushed DC motors. The small footprint of the controller fits down inside the channel and the mounting holes perfectly align with the hub pattern which perforates the Actobotics® building system. This controller has 4 selectable modes.


  1. Actobotics Dual Motor Driver Board
  2. Jumpers
  3. Screw Terminals (pre-assembled on board)


Four Selectable Modes:

(1) Digital Speed Control Mode (RC Mode):
The motor’s speed and direction will be controlled by a 1000 - 2000 µs digital PWM signal.
1000 µs = 100% in one direction
1500 µs = No movement
2000 µs = 100% in the other direction

(2) Analog Speed Control Mode:
The motor’s speed and direction will be controlled by an analog voltage. The voltage is commonly controlled by a potentiometer. We recommend one with at least 1K of resistance such as our 5K potentiometer board.
0V = 100% in one direction
1.65V = No movement
3.3V = 100% in the other direction

(3) Split Mode:
Channel 1 operates in Position Control Mode while Channel 2 operates under Digital Speed Control Mode.

(4) Position Control Mode (Servo Mode):
In this mode the motor controller acts like a servo controller. Both channels will utilize a PWM signal as the target position, and an analog voltage (usually via a potentiometer) as the current position. If the current position does not match the target position the motor will be driven until they match.
