A3967 Stepper Motor Driver For Arduino

A3967 Stepper Motor Driver For Arduino is the latest version of EasyDriver v44 co-designed with Brian Schmalz. It provides greater flexibility and control over your stepper motor compared to the 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.

This Stepper Motor Driver For Arduino 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 Easy Driver).

A3967 Stepper Motor Easy Driver requires a 7V to 30V supply to power the motor and can power any voltage of stepper motor. The Easy Driver 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 micro-controller and you’ve got precision motor control! Easy Driver 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.

Features:

• A3967 microstepping motor 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
• 3.0 to 5.5V logic supply

Specifications:

• Voltage Rating (V):: 7 to 30VDC
• Current Rating (A):: 0.15 to 0.75
• Input Voltage (VDC): 7 to 30
• Logic Voltage (V): 3.3 ~ 5
• Length (mm):: 48
• Width (mm):: 20

Package Included:

• 1 x A3967 Stepper Motor Driver For Arduino

Note:

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