A4988 Stepper Motor Driver Module with heatsink – ideal for controlling stepper motors in 3D printers, CNCs, and Arduino projects with precision and reliability.
The A4988 Stepper Motor Driver Module is a compact and powerful solution for controlling bipolar stepper motors. It supports full, half, quarter, eighth, and sixteenth step modes for precise motion control. Designed for use with Arduino, CNC machines, 3D printers, and other microcontroller-based projects, it features overcurrent protection, thermal shutdown, and crossover current protection for reliable operation.
This module can drive stepper motors with up to 2A per coil (with proper cooling) and includes an onboard potentiometer for adjusting current output. The included heatsink ensures stable performance during long runs.
Key Features:
✔️ Adjustable current control via onboard potentiometer
✔️ Up to 1/16 microstepping for smooth motion
✔️ Supports 8V–35V input voltage
✔️ Compatible with most 3D printer and CNC applications
✔️ Comes with detachable heatsink
