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). EasyDriver requires a 6V to 30V supply to power your motor and can power a stepper motor of any voltage. 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.
The microstep select (MS1 and MS2) pins of the A3967 are broken out, allowing adjustments to the microstepping resolution. The sleep and enable pins also are 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.
Compared to the previous version of the EasyDriver, this version has slightly different power ratings and better over-voltage protection. For most applications the function should be identical.
EasyDriver Stepper Motor Driver 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 700mA/phase
- Power supply range from 6V to 30V. The higher the voltage, the higher the torque at high speeds
