A4988 Stepper Motor Driver Module – Precision Control for CNC & 3D Printers

(Compatible with RAMPS, CNC Shield, and DIY Robotics Projects)

🔧 Perfect for CNC Machines, 3D Printers & Robotics

The A4988 stepper motor driver delivers precise microstepping control for bipolar stepper motors (up to 2A per phase). Designed to work with CNC shields, RAMPS 1.4, and Arduino-based projects, this compact driver ensures smooth, vibration-free motion in your CNC routers, 3D printers, and automated systems.

🚀 Key Features

✔ Microstepping Control – Supports full, half, 1/4, 1/8, and 1/16 step modes
✔ Wide Voltage Range – 8V to 35V DC input (2A max per coil)
✔ Overheat Protection – Thermal shutdown with internal circuitry
✔ Adjustable Current Limit – Set VREF via potentiometer for optimal motor performance
✔ Compact & Efficient – Fits standard CNC shields (plug-and-play)
