DescriptionThis CJMCU relay and stepper motor driver module is a breakout board for ULN2803A, which is a high-voltage, high-current Darlington transistor array. The device includes eight NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The collector-current rating of each Darlington pair is 500mA. The Darlington pairs can be connected in parallel manner for higher current capability.If you want to control a DC motor using Arduino, you must use some kinds of drivers such as ULN2803. Controlling a DC motor using ULN2803 is very easy, but it has a problem, you can't change the direction of rotation of motor by this circuit.
