I’m doing some research on A4983 Driver with the built in Voltage regulars and some bi-polar stepper motors before making a purchase. There was a 3.9 volt, 600mA bi-polar stepper motor that caught my eye. However, after reading the specification for the motor supply that needed 8-35 volts for the A4983 Driver I was doubting if I could use it. I know I could adjust the current with the onboard potentiometer. However, I was wondering if I could add a resistor to create a voltage drop for the bi-polar stepper motor, or is there another method?
