DC 7V To 30V 150mA To 750mA A3967 Easy Driver Stepper Motor Driver Board

Description 1 The EasyDriver is a simple to use stepper motor driver compatible with anything that can output a digital 0V to 5V pulse or 0V to 3 3V pulse if you solder SJ2 closed on the EasyDriver 2 EasyDriver requires a 7V to 30V supply to power the motor and can power any voltage of stepper motor 3 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 youve got precision motor control EasyDriver drives bi polar motors and motors wired as bi polar I e 4 6 or 8 wire stepper motors 4 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 cjmcu made Features 1 MS1 and MS2 pins broken out to change microstepping resolution to full half quarter and eighth steps defaults to eighth 2 Compatible with 4 6 and 8 wire stepper motors of any voltage3 Adjustable current control from 150mA phase to 750mA phase4 Power supply range from 7V to 30V The higher the voltage the higher the torque at high speeds5 Distribution pin not welded this module is open source Note Do not connect or disconnect a motor while the driver is energized This will cause permanent damage to the A3967 IC Chip data http www alldatasheetcn c
