A4988 Features:

Simple step and direction control interface

Short-to-ground and shorted-load protection

Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step

Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)

Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection

Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated
voltage to achieve higher step rates.
