Features of ULN2003 BASED Stepper motor driver board:
ULN2003 Stepper Motor Driver Board is compact
It uses the ULN2003 driver chip to amplify the control signal from the Arduino and other MCU used.
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 stepper motor is used to convert pulse to angular displacement. So if you give the stepper driver a certain pulse signal, it will drive the stepper motor to a certain angle. you can control the angle of the stepper motor by adjusting the number of pulses. And you also can control the speed of the stepper rotation by the frequency of the pulse.
Connections:
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.
