Can you use a stepper motor driver for a DC motor?

To answer your question, yes you can run two DC motors of A4988 Module because the output stages that are driving a bipolar stepper winding are H-bridges and you need two of them (Check here for more on bipolar motors) . Controlling two motors with different speeds is out of mind.

How do you run a DC motor?

DC motors normally have just two leads, one positive and one negative. If you connect these two leads directly to a battery, the motor will rotate. If you switch the leads, the motor will rotate in the opposite direction.

Why stepper motor is a DC motor?

The stepper motor works similarly to brushless DC motors, except that it moves in much smaller steps. Its only moving part is also the rotor, which contains the magnets. An alternating current controls the polarity of each coil. As the polarity changes, each coil gains push or a pull effect, thus moving the motor.
