Introduction: A stepper motor is a permanent magnet synchronous motor that requires the magnetic field to be electronically switched through an external control circuit. This is easily accomplished by utilizing the Samotronic driver board.

	Quick start up procedure:

1. Please unpack the PCB in an electrostatic discharge (ESD) free environment.

2. Connect a unipolar stepper motor to the 6 pin, MTA100-receptacle, terminal (B).

3. Ensure the configuration settings of the DIP-switch (C) are as shown in the figure below.

4. Adjust the step frequency to the minimum setting by rotating the potentiometer (D) about 10 times in the counter clockwise direction.

5. Choose a regulated power supply and adjust the voltage that matches the stepper motor's required input. For example, a 12v motor would require you to adjust the power supply to 12v DC. Do not apply a voltage to the driver board that exceeds 24v DC.

6. Be careful of the polarity and connect the power supply wires to terminal (A), positive (+) to pin 7 and negative or GND (-) to pin 1.

7. Turn the power supply on and the motor will begin to move.
