Description

42 Stepper Motor Driver Expansion Board DRV8825 A4988 3D Printer Control Shield Module For Arduino UNO R3 Ramps1.4 DIY Kit One

Upgrade your 3D printer or CNC machine with our dual‑driver expansion board, engineered to deliver precise motion control and high reliability. Designed for both the popular DRV8825 and A4988 stepper drivers, this shield plugs directly into your Arduino UNO R3 or RAMPS 1.4 board, giving you instant access to advanced microstepping, current limiting, and thermal protection.

Product Overview

This compact, DIY-friendly module features two breakout sockets for DRV8825 or A4988 drivers, a built‑in heat sink, and a 3.3 V/5 V power switch. It’s perfect for hobbyists, makers, and professionals looking to build or upgrade a 3D printer, laser cutter, or robotic arm.

Key Highlights

• Dual Driver Support – Plug in two DRV8825 or A4988 stepper drivers for full X/Y/Z axis control.
• Microstepping Flexibility – 1/16, 1/8, 1/4, 1/2, and full steps for smooth motion.
• Current Limiting – Adjustable potentiometer to set the motor current for optimal torque and heat management.
• Heat Sink & Thermal Protection – Built‑in heat sink keeps drivers cool; thermal shutdown prevents damage.
• Easy Installation – 0.1” pitch headers, no soldering required for most setups.
• Compatible with Arduino UNO R3 & RAMPS 1.4 – Works out of the box with popular 3D printer firmware (Marlin, Repetier, etc.).
• Power Switching – 3.3 V/5 V selector for low‑voltage or high‑voltage stepper drivers.
• Robust Build – PCB material and components rated for 10 A continuous current.
