Brand Manolins Model A3967 Quantity 1 Color Red Material PCB Specification A3967 Chip; Power Supply: 7V~30V Features Compatible with 4 6 and 8 wire stepper motors of any voltage Application 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). It requires a 7V to 30V supply to power the motor and can power any voltage of stepper motor. 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. Note: Do not connect or disconnect a motor while the driver is energized. This will cause permanent damage to the A3967 IC. English Manual/Spec Yes Other Compatible with 4 6 and 8 wire stepper motors of any voltage; Adjustable current control from 150mA/phase to 750mA/phase; MS1 and MS2 pins broken out to change microstepping resolution to full half quarter and eighth steps (defaults to eighth); Power supply range from 7V to 30V. The higher the voltage the higher the torque at high speeds Packing List 1 x EasyDriver Shield
