Description

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

• The most easy module to learn how to control the Stepper and finish the simple project.
• The logic control voltage:3~5.5V
• Motor Supply Voltage: 5~ 15V
• it can sink 500mA from a 50V supply,but you'd better limit the driver voltage under 15v.
• Operating temperature: -25 degree Celsius ~ +90 degree Celsius

HOW TO CONTROL STEPPER

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.
