Advanced Stepper Motor Driver

This stepper motor driver can control 2 phase bipolar stepper motors of 4, 6 or 8 wires. It's compatible with anything that can generate a 0-5V pulse like a microcontroller or pulse generator IC. It's very easy to use and gives you maximum control over your stepper motor. 

The heart of this driver board is a A3967 IC, which is generally used in 3D printers & other CNC machines and incorporates reduced audible motor noise, increased step accuracy & very low power loss. As a minimum, this stepper driver requires only one digital pin of a microcontroller to control a bipolar stepper motor. Although, complete control requires 3 digital pins.  

Current control, which is a very important concern while driving a stepper motor, can be achieved very easily by this chopper driver. You just have to rotate a potentiometer placed on this board to set the output current limit. You can also choose from various step sizes (full, half, quarter, 1/8 th) by adjusting the onboard DIP switches.

To know how to use this driver, please go through the user manual. (check Documents section)

Note: This driver can only control bipolar steppers of 2 phase. Unipolar stepper motors or bipolar steppers of more than 2 phases aren't supported.

Caution: 

1. Do not disconnect motor while the board is energized / powered up.

2. Do not power up this driver board when no compatible motor is connected.

These will cause permanent damage to the A3967 IC. Always make sure that there's a motor connected in correct way before connecting or disconnecting a power source. And disconnect motor only after disconnecting the power source.
