Original Chip A4988 Stepper Motor Driver (Red) with Heatsink – 1.5A

The A4988 Stepper Motor Driver is a highly efficient micro-stepping motor driver with a built-in translator for easy control. It is designed to operate stepper motors in full, ½, ¼, ⅛, and 1/16 step modes, offering precise movement control. With an input voltage range of 8V to 35V, it can deliver up to 1A per phase without additional cooling, and up to 2A with proper heat dissipation.

This driver is ideal for CNC machines, 3D printers, robotics, and automation projects. It requires no complex programming for phase sequence or high-frequency control, making it perfect for simple microcontroller-based applications.
