DIYables A4988 Stepper Motor Driver Module with Heat Sink, Presoldered Stepstick Stepper Controller
Click to zoom
Quick Overview
The DIYables A4988 Stepper Motor Driver Module is a high-performance stepstick stepper controller designed for precise motor control in 3D printers, CNC machines, and robotics projects. Featuring a simple step and direction interface, this presoldered driver module works seamlessly with Arduino, ESP32, ESP8266, Raspberry Pi, and other microcontrollers. The A4988 chip operates at 8V to 35V and delivers up to 2A per coil with intelligent chopping control for stable and efficient stepper motor operation.
This 2-pack module comes with heat sinks pre-installed and supports five microstepping resolutions: full step, half step, quarter step, eighth step, and sixteenth step for smooth and precise motor movement. The built-in potentiometer allows adjustable current limiting to protect your stepper motor and driver from overcurrent damage. Multiple safety features include over-temperature shutdown, under-voltage lockout, and cross-current protection ensuring reliable long-term operation.
Perfect for 3D printer projects (Reprap, RAMPS 1.4), CNC machines, robotics, automation systems, and any application requiring precise stepper motor control. The presoldered design makes it ready to use out of the box with Arduino, ESP32, ESP8266, Raspberry Pi, and other microcontroller platforms for motion control applications.
