ULN2003 Stepper Motor Driver Module

This is a ULN2003 Driver Module Stepper Motor Driver, small size, and easy to use. It uses the ULN2003 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: The colour of PCB may vary according to the Manufacturer. Technical Specifications: motor driver chip: ULN2003A Power supply: 5-12V Signal indicator: 4-way Step angle: 5.625 x 1 / 64 Reduction ratio: 1 / 64 Phase: 4 Current / Phase: 5V Chip all the pins already leads for easy connection to use 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 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.
