This product is a breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection; please read the A4988 datasheet carefully before using this product.

This stepper motor driver allows 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.

The translator is key to the easy implementation of the A4988.

Simply inputting one pulse on the STEP input drives the motor one microstep.

There are no phase sequence tables, high-frequency control lines, or complex interfaces to program.

The A4988 interface is an ideal fit for applications where a complex microprocessor is unavailable or overburdened.
