Stepper Motor Driver (A4988) - Module with Heatsink

Stepper Motor Driver (A4988) – Module with Heatsink Product Description The A4988 Stepper Motor Driver Module is a compact and efficient microstepping motor driver designed to control bipolar stepper motors with precision and ease. Based on the Allegro A4988 driver IC, it supports adjustable current limiting, over-current protection, thermal shutdown, and multiple microstepping modes for smooth and accurate motor control. The module is widely used in 3D printers, CNC machines, laser engravers, robotics, and automation projects. It is fully compatible with Arduino CNC Shield V3, RAMPS 1.4, and other Pololu-compatible driver sockets. This version includes an aluminum heatsink for improved heat dissipation during continuous operation. Features Based on the Allegro A4988 stepper motor driver IC Controls one bipolar stepper motor Supports full-step, half-step, 1/4, 1/8, and 1/16 microstepping Adjustable output current via onboard potentiometer Built-in over-current and short-circuit protection Thermal shutdown and under-voltage lockout protection STEP and DIR interface for easy control Pololu-compatible pin layout Includes aluminum heatsink for better cooling
