Features of ULN2003 BASED Stepper motor driver board:

ULN2003 Stepper Motor Driver Board is small size and easy to use

It uses the ULN2003 driver chip to amplify the control signal from the Arduino and other MCU.

Commonly used to run and control the small applications stepper motors.

It uses the ULN2003 DARLINGTON ARRAYS to drive the 4-phase 5-wire stepper motor ( 5v to 12v ).

Compatible with  Arduino or other development platform to drive the stepper motor.

How to Control Stepper:-


The step motor is to a machine to convert pulse to angular displacement. So if you give stepper driver a certain pulse signal, it will drive step motor to a certain angle. you can control the angle the stepper moved by the number of the pulse. And you also can control the speed of the stepper rotate by the frequency of the pulse.



IN1-4 to the Microcontroller Pins

The pins in the white jack (from left to the right) are: VCC, A, B, C, D (to the stepper motor)

Power pins are on the right, use jumper to choose either 5V or 12V.
