The EasyDriver is a simple to use stepper motor driver that can driver up to about 750mA per phase of a bi-polar stepper motor. EasyDriver requires a 7V to 30V supply to power the motor and can power any voltage of stepper motor. The EasyDriver 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! EasyDriver drives bi-polar motors, and motors wired as bi-polar. I.e. 4,6, or 8 wire stepper motors. It is a chopper microstepping driver based on the Allegro A3967 driver chip, 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.
- Based on the 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
