This product is a carrier board or breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection; we therefore recommend careful reading of the A4988 datasheet (1MB pdf) before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil (see the Power Dissipation Considerations section below for more information). Here are some of the driver’s key features:

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 to achieve 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

This carrier has reverse power protection on the main power input and built-in 5 V and 3.3 V voltage regulators that eliminate the need for separate logic and motor supplies and let you control the driver with microcontrollers powered at 5 V or 3.3 V. We also sell a smaller, higher-performace version of the A4988 carrier without voltage regulators.
