A4988 Stepper Motor Driver Module with Heatsink

A4988 Stepper Motor Driver Module with Heatsink

Power your project’s motion with the industry-standard A4988 Stepper Motor Driver. This versatile and highly popular module provides a simple and reliable solution for driving bipolar stepper motors. It’s the go-to choice for countless 3D printers, small CNC mills, and robotics projects worldwide due to its excellent performance and affordability.

The A4988 driver simplifies complex motor control down to just two pins: one for controlling the step and another for the direction. With five selectable step resolutions (full-step, half-step, 1/4-step, 1/8-step, and 1/16-step), you can achieve smooth and precise movements tailored to your application’s needs. The onboard potentiometer allows you to easily set the maximum current output to protect your motor from over-current damage.

This module is designed for easy integration and comes with built-in protection features, including thermal shutdown and crossover-current protection. For optimal performance under load, a self-adhesive aluminum heatsink is included to help dissipate heat from the driver chip.

Key Features:

• Driver Chip: Allegro A4988
• Motor Voltage: 8V to 35V DC
• Logic Voltage: 3.3V to 5.5V compatible
• Max Current: Up to 2A per coil (with proper cooling and heatsink)
• Microstepping Resolutions: Full, 1/2, 1/4, 1/8, and 1/16
• Protection: Thermal shutdown and crossover-current protection
• Interface: Simple step and direction (STEP/DIR) interface
• Form Factor: Compact “stepstick” for easy integration
• Included: A4988 Module & self-adhesive Aluminum Heatsink

Applications:

The A4988 driver is perfect for a huge range of applications, including FDM 3D printers (like Prusa i3, Anet A8), small CNC routers, laser engravers, robotic arms, camera sliders, and any project that requires precise control of a NEMA 17 or similar stepper motor.
