Product Description

A4988 Stepper Motor Driver Module

Specification:

This stepper motor driver module is a breakout/carrier board for Allegro's A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection and is Pololu / StepStick compatible. This stepper motor driver lets you control a bipolar stepper motor at 1 A continuous current per phase without a heatsink or cooling, and at up to 2 A maximum output current per coil if additional cooling is provided. An onboard potentiometer is used to adjust the current output.

Minimum operating voltage: 8V

Maximum operating voltage: 35V

Continuous current per phase: 1A

Maximum current per phase: 2A (with cooling)

Minimum logic voltage: 3V

Maximum logic voltage: 5.5V

Thermal shutdown circuitry

Ground fault protection

Load short-circuit protection

Microstep resolutions: Full, 1/2, 1/4, 1/8 and 1/16
