This is ULN2003A Driver Module Stepper Motor Driver, small size and easy to use. It uses the ULN2003A driver chip to amplify the control signal from the Arduino. This Ultra Lightweight and cheap option commonly used to run and control the small applications stepper motors. Note: Color of PCB of may vary according to Manufacturer 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. The following picture is the schematic of the stepper driver. The following picture is the control signal to drive a 28BYJ48 stepper to rotate 1/4096 circle. line 1 2 3 4 5 6 7 8 red 1 1 1 1 1 1 1 1 orange 1 1 0 0 0 0 0 1 yellow 0 1 1 1 0 0 0 0 pink 0 0 0 1 1 1 0 0 blue 0 0 0 0 0 1 1 1 Note: We have small size 28BYJ-48 Stepper Motor available in our shop which can be coupled with this ULN2003A Driver Module, click below to buy 28BYJ-48 Stepper Motor Features 4-way signal indicator Chip all the pins have Input leads Mounted for easy connection to use XH-5P socket can be connected directly 28BYJ-48 Model stepper motor
