x2pcs A3967 EasyDriver Stepper Motor Driver V44 for Development Board 3D Printer
DESCRIPTION:
Stepper motor step angle is usually defined with parameters or a number of steps, the general motor revolution is divided into 200 steps, which is the step angle of 1.8 degrees, EasyDriver subdivision function with a step, this driver board subdivision 8 segments, that is, each step of the motor is subdivided into 8 small step, this can be more precise control, ie EasyDriver to 1600 steps to complete a full 360 degree rotation.
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 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 micro controller and 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.
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 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.
