A4988 Stepper Motor Driver

The A4988 Stepper Motor Driver is a microstepping bipolar stepper motor driver capable of up to 1/16 microstepping. It provides smooth, precise motion control for 3D printers, CNC machines, and positioning systems.

Key Features

Up to 1/16 microstepping for smooth motion
2A per coil max with adequate cooling
Adjustable current limiting via potentiometer
Multiple step resolutions: full, 1/2, 1/4, 1/8, 1/16
Protections: over-temperature, over-current, short-circuit
STEP/DIR interface for simple control
Auto current decay mode detection

Technical Specifications

Parameter Specification

Model A4988 (Pololu-compatible)

Motor Type Bipolar stepper

Max Current 1A per coil (2A with heatsink)

Microstepping Full, 1/2, 1/4, 1/8, 1/16

Logic Voltage 3.3V – 5V

Motor Voltage 8V – 35V

Interface STEP, DIR, ENABLE, MS1-MS3

Protection Thermal shutdown, overcurrent

Dimensions 15mm x 20mm

Applications

3D printer control (RAMPS, Rumba boards)

CNC machine axes

Camera sliders and dollies

Automated dispensers

Positioning tables

Precision linear actuators

Important Notes

CRITICAL: Adjust current limit BEFORE connecting motor – measure Vref

Formula: Current Limit = Vref × 2.5 (for standard 0.05Ω sense resistors)

Heatsink + fan REQUIRED for currents above 1A

Enable pin is active LOW – leave disconnected to enable

Do not disconnect motor while powered – will destroy driver

MS1, MS2, MS3 pins set microstep resolution (see datasheet)
