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 authentic, engineering-grade hardware component designed for prototyping, robotics, and academic research. Includes verified schematics, pre-tested hardware, 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
Quick Build & Interfacing Guide:
Unbox and verify all pre-tested sensors, microcontrollers, and wiring components included in your package.
Secure mechanical brackets, servos, and modules to the main frame using the provided mounting hardware.
Interface VCC, GND, and GPIO signal lines according to the verified schematic diagram provided with the kit.
Upload the tested source code via Arduino IDE, Python, or ESP-IDF and verify live sensor readings and actuation.
