Features:
This product is a breakout board for A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection.
This stepper motor driver lets you to operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes,
with an output drive capacity of up to 35 V and +/- 2 A

Maximum output current is 1A
Simple step and direction control interface
Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
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 toachieve higher step rates
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
Short-to-ground and shorted-load protection
