Description
The A4988 Stepper Motor Driver Module with Heatsink is a compact breakout board based on Allegro’s A4988 DMOS microstepping driver, designed to control bipolar stepper motors with precision and efficiency. Operating from 8V to 35V, it delivers up to 1A per phase without cooling and 2A per coil with a heatsink or forced airflow, making it compatible with motors like NEMA17, NEMA23, or NEMA34 (4-, 6-, or 8-wire configurations). The module supports five microstepping resolutions—full-step, half-step, quarter-step, eighth-step, and sixteenth-step—via MS1, MS2, and MS3 pins, enabling smooth motion (e.g., 800 microsteps/rev for a 200-step motor in quarter-step mode). An onboard potentiometer adjusts current limiting
