The A3967 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 A3967). A3967 requires a 7V to 30V supply to power the motor and can power any voltage of stepper motor. The A3967 has an on board voltage regulator for the digital interface that can be set to 5V or 3.3V. Connect a 4-wire stepper motor and a microcontroller and you've got precision motor control! A3967 drives bi-polar motors, and motors wired as bi-polar. I.e. 4,6, or 8 wire stepper motors. On this version (v4.4) we fixed the silk error on the min/max adjustment. It provides much more flexibility and control over your stepper motor, when compared to older versions. The microstep select (MS1 and MS2) pins of the A3967 are broken out allowing adjustments to the microstepping resolution. The sleep and enable pins are also broken out for further control.

Note: Do not connect or disconnect a motor while the driver is energized. This will cause permanent damage to the A3967 IC.

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

What type of motors are compatible with the driver?

It supports bi polar stepper motors with 4, 6, or 8 wires and can power motors from 7 to 30 V. The digital input accepts 0 to 5 V pulses, or 0 to 3.3 V when SJ2 is closed.

How do I set the microstepping and current?

Microstep resolution is set by MS1 and MS2 pins, allowing full, half, quarter, and eighth steps. Current is adjustable from 150 mA per phase to 750 mA per phase.

What voltage and power supply are required?

Requires 7 to 30 V supply to power the motor. The digital interface voltage can be set to 5 V or 3.3 V using the built in regulator.

Are there safety considerations when wiring or powering the device?

Yes, do not connect or disconnect a motor while the driver is energized to avoid permanent damage.
