3967 Stepper Motor Driver For Arduino is the latest version of Easy Driver v4.4. It provides greater flexibility and control over your stepper motor compared to the older versions.It is a simple to use stepper motor driver, compatible with most microcontrollers that can output a digital 0 to 5V pulse (0 to 3.3V pulse if you solder SJ2 closed on the Easy Driver). The module requires a 7V to the 30V power supply for a motor. The module has an onboard voltage regulator for the digital interface that can be set to 5V or 3.3V.Features of A3967 Stepper Motor Driver Module:-A3967 Precision Micro stepping Driver.MS1 and MS2 pins broken out to change micro stepping resolution to full, half, quarter and eighth steps (defaults to eighth).Compatible with 4, 6, and 8 wire bipolar stepper motors such as popular NEMA 17.

Adjustable current control from 150mA/phase to 750mA/phase.Compatible with Arduino GRBL G-code interpreter for driving 3-axis CNC machines.Breadboard compatible pins.Power supply range from 7V to 30V. The higher the voltage, the higher the torque at high speeds.
