927706 EasyDriver Stepper Motor Driver Description: 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 7V to 20V 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. On this
version (v4.4) we fixed the silk error on the min/max adjustment.
This is the newest version of EasyDriver V4 co-designed with Brian Schmalz.
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. The sleep and enable pins are also broken out for further
control.
Note: Do not connect or disconnect a motor while the driver is energized. This will cause permanent damage to the A3967 IC.
Note: This product is a collaboration with Brian
Schmalz. A portion of each sales goes back to them for product support
and continued development.
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 750mA/phase
- Power supply range from 7V to 20V. The higher the voltage, the higher the torque at high speeds
