Introduction

We design this driver basically for using to drive the 28BYJ48-5V stepper motor. This stepper motor is a unipolar type stepper. But you can also use it to drive a 2 phase bipoloar stepper.

Usage

The pin definition of the board are as following picture. [[file:|400px]] The uln2003A is like an inverter. When you input an HIGH voltage at the input pin, then the relative output pin will output a LOW voltage. So please note this when you use it to drive an stepper motor.
