A3967 EasyDriver Stepper Motor Driver Module

A3967 EasyDriver Stepper Motor Driver Module for Arduino development board and 3D Printer

Introduction

• EasyDriver drives bi-polar motors, and motors wired as bi-polar. I.e. 4,6, or 8 wire stepper motors.
• The EasyDriver has an on board voltage regulator for the digital interface that can be set to 5V or 3.3V.
• EasyDriver requires a 7V to 30V supply to power the motor and can power any voltage of stepper motor.
• Connect a 4-wire stepper motor and a microcontroller and you’ve got precision motor control.
• The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver).

Features

• A3967 microstepping driver
• MS1 and MS2 pins broken out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth)
• Compatible with 4, 6, and 8 wire stepper motors of any voltage
• Adjustable current control from 150mA/phase to 750mA/phase
• Power supply range from 7V to 30V. The higher the voltage, the higher the torque at high speeds
