A4988 Stepper Motor Driver Module with heat sink

Overview of this  A4988 Stepper Motor Driver Module with heat sink

Introducing Roboway A4988 stepper motor driver at the best price in India with Roboway. This A4988 is a tiny yet powerful motor driver board it is designed to control stepper motors in your DIY electronics and robotics projects. It allows you to move stepper motors in small and accurate steps, making it ideal for 3D printers, CNC machines, and other motion control systems.

It comes with a heat sink for cooling and this version includes a small aluminum heat sink to help reduce overheating during continuous motor operation, improving performance and lifespan. It supports full-step, half-step, quarter-step, eighth-step, and sixteenth-step resolutions for smoother and quieter motor movement.

Features

Built-in Translator – You can control the motor with just step and direction signals, making it easy to use with Arduino or other controllers.

Adjustable Current Control – You can set the max motor current using a small screw (potentiometer), so your motor doesn’t overheat.

Five Microstepping Modes – It supports Full, Half, 1/4, 1/8, and 1/16 stepping for smooth and precise motor movement.

Over-Temperature Protection – It automatically shuts down the driver if it gets too hot, keeping your components safe.

Onboard Heat Sink –  It helps keep the driver cool during long or heavy use.

Wide Voltage Range (8V to 35V) – It can be used with many different power supplies.
