EasyDriver A3967 Stepper Motor Driver Module

Description:
The EasyDriver is a simple to use stepper motor driver, compatible with anything that can produce a 0-5V digital pulse (or 0-3.3V if you solder SJ2 closed to the EasyDriver). EasyDriver requires a 7V to 30V power supply to power the motor and can power any voltage of the stepper motor. The EasyDriver has a built-in voltage regulator for the digital interface which can be set to 5V or 3.3V. Connect a 4-wire stepper motor and microcontroller and you have precision motor control. EasyDriver runs bipolar motors and wired motors as bipolar. For example: 4, 6 or 8 stepper motors On this version (v4.4), we fixed the silk error on the min/max setting.
This is the latest version of EasyDriver V4 designed with Brian Schmalz. It offers much more flexibility and control over your stepper motor, compared to earlier versions. The microstep selection pins (MS1 and MS2) of the A3967 are broken down allowing adjustments to the microstepping resolution. Sleep and activation pins are also broken for more control.
Remarks:
Do not connect or disconnect an engine while the driver is powered on. This will cause permanent damage to IC A3967.
Remarks:
This product is a collaboration with Brian Schmalz. Part of each sale comes to them for product support and continuous development.
Features:
A3967 microstep driver.
Broken MS1 and MS2 pins to change micro-step resolution in full step, half-quarter and eighth steps (default to eighth)
Compatible with 4, 6 and 8 wire stepper motors of any voltage.
Adjustable current control from 150mA/phase to 750mA/phase.
Power range from 7 V to 30 V. The higher the voltage, the higher the torque at high speed.
