The Mini Stepper Driver is small size and easy to use. It used ULN2003 to amplify the control signal from the Arduino. The Drive voltage can up to 15v.
Features
Step motor is to a machine to convert pulse to angle 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.
This usage is to drive a 28BYJ stepper. The stepper stopped when pushed the stop_button. It also can be changed to control the stepper to counterclockwise or clockwise rotate. Connect 28BYJ step motor to mini stepper driver as below:Stepper ControlÝ kiến bạn đọc
