• No additional interface circuit is required between the a3967slb and the microprocessor. The chip adopts easystepper.
  The interface reduces the number of eight control lines by two (step and direction). By simply inputting the pulses that control the stepper motor, the embedded converter can control the stepper motor.
  A3967slb also needs some resistors and capacitors to adjust its operating parameters, the whole drive circuit is very simple
