A4988 Stepper Motor Driver Module with Aluminum Heat Sink
Complete microstepping motor driver with built-in translator for 3D printers (RAMPS 1.4), CNC routers, and precise robotics automation.
A4988 Stepper Motor Driver Module with Aluminum Heat Sink is an original, pre-tested electronic module designed for Arduino, ESP32, Raspberry Pi, robotics, and embedded engineering projects. Includes verified pinout compatibility and nationwide express shipping across Pakistan.
The A4988 Stepper Motor Driver carrier board is the industry benchmark for controlling bipolar stepper motors in 3D printers, CNC laser engravers, and robotic joints.
Key Engineering Features:
- Built-in Translator: Simple two-pin interface (STEP and DIR) drastically simplifies microcontroller firmware.
- Five Microstep Resolutions: Full-step, 1/2-step, 1/4-step, 1/8-step, and 1/16-step for smooth, whisper-quiet motor motion.
- Adjustable Current Limiting: Precision onboard potentiometer sets the maximum output current to prevent motor overheating.
- Intelligent Chopping Control: Automatically selects correct current decay mode (fast decay or slow decay).
Common Engineering Applications:
- 3D Printers (Creality, RepRap, Prusa, RAMPS 1.4, CNC Shield v3)
- Desktop CNC milling machines and laser cutters
- Camera sliders, pan-tilt heads, and optical focus mounts
- Industrial automated pick-and-place equipment
What's Included in the Package:
- 1x A4988 Stepper Motor Driver Module
- 1x Aluminum Heat Sink with Pre-applied Thermal Conductive Adhesive
Pinout Interfacing & Testing Guide:
Check the silkscreen pin labels (VCC, GND, SDA/SCL or I/O) and confirm whether your microcontroller uses 3.3V or 5V logic.
Wire the power, ground, and signal pins to your Arduino, ESP32, or Raspberry Pi using breadboard jumper wires.
Upload a standard test sketch via Arduino IDE or MicroPython and verify live readings on the Serial Monitor.
