DRV8825 Stepper Motor Driver (2.5 A - Ramps Compatible)

Overview

Upgrade your 3D printer or CNC machine with the DRV8825 stepper motor driver, a high-performance module designed for precise and quiet motor control. This driver supports up to 2.5A per coil and offers adjustable current limiting, making it a versatile choice for a wide range of stepper motors. With built-in micro-stepping (down to 1/32 step) and protection features like over-temperature and over-current, the DRV8825 is a reliable and efficient solution for your motion control projects. Its compatibility with RAMPS and other popular controller boards makes it an essential component for any maker, hobbyist, or professional.

Key Features

• High Current Capacity: Supports up to 2.5A per coil, suitable for most NEMA 17 and NEMA 23 stepper motors.
• Micro-Stepping: Provides full-step to 1/32-step resolutions for smoother and more precise motion.
• Adjustable Current Limiting: Easily set the motor current with a potentiometer to match your motor's specifications.
• Built-in Protection: Over-temperature, over-current, and under-voltage lockout protect your driver and motor.
• Low Power Dissipation: Low RDS(on) MOSFETs reduce heat generation, improving efficiency.
• Compact Design: Small form factor with standard pinout, ideal for RAMPS and other 3D printer boards.
