This is the newest version of EasyDriver V4, and it provides much more flexibility and control over your stepper motor, when compared to the older versions. The microstep select (MS1 and MS2) pins of the A3967 are broken out, so you can adjust the microstepping resolution. The sleep and enable pins are also broken out for further control. Caution: 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 eigth steps Compatible with 4, 6, and 8 wire stepper motors Adjustable current control from 150mA/phase to 750mA/phase Power supply range from 7V to 30V. The higher the voltage, the higher the torque. Documents: Schematic A3967 Datasheet EasyDriver Website Example Stepper Motor Control Example Arduino Tutorial in Portuguese
