Products for USB Sensing and Control
This 50g-cm unipolar stepper motor is good for light jobs such as turning small knobs.
This motor must be controlled by a stepper motor controller. The following table shows how to connect the motor wires to the board connectors to produce a clockwise rotation in the stepper motor when increasing position.
To connect the motor to a bipolar motor controller, leave out the orange and brown wires.
Note: Make sure to unplug the power cord from the controller board before switching wires around.
