The A4988 Stepper motor driver is used to control medium and larger stepper motor like those used in 3D printers, CNC machines and in robots.
In this tutorial I give a detailed explanation of the pinout of this motor driver, how to find the Current Limit of A4988 Stepper motor driver by measuring the Reference Voltage and how this driver can be used with the Arduino Microcontroller to drive bipolar stepper motors.
