These specifications are drawn from the pictured bare board; do not assume the same current, frequency or terminal layout for every version. Choose the input voltage specified for your selected option and match the motor's own rating.
Applications
Suitable for controlling the speed of compatible small brushed DC motors in projects and equipment, within the ratings of the chosen controller and motor.
What's Included
One controller in the selected configuration. The illustrated motor, battery and connecting wires are for wiring reference and are not included.
Installation
Use a DC supply only; never connect the controller directly to AC mains. Observe input polarity. On the illustrated bare board, connect the supply and motor to the corresponding terminals shown in the diagram. Reversing the motor leads changes its rotation direction. Disconnect power before changing wiring and avoid exceeding the controller or motor ratings.
