a4988 stepper motor Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection.
stepper damper module Five different step resolutions full-step, half-step, quarter-step, eighth-step, and sixteenth-step.
stepper motor driver Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motors rated voltage to achieve higher step rates
3d printer stepper motor driver Short-to-ground and shorted-load protection.
a4988 Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay).
