Arduino Nano CNC Shield V4 Expansion Board – 3-Axis Stepper Motor Driver Shield for Engraving & 3D Printing

Overview

The Arduino Nano CNC Shield V4 is an ultra-compact expansion board designed to transform an Arduino Nano into a highly functional 3-axis motion controller. Operating seamlessly with open-source GRBL firmware, this shield serves as the main control hub for micro-CNC machines, laser engravers, and automated camera sliders.

By eliminating complex wiring webs, it allows you to easily slot in three plug-and-play stepper drivers. Its small form factor makes it ideal for portable projects, custom 3D-printed enclosures, and school or university robotics assignments where space and weight are strictly limited.

Key Features

• 3-Axis Independent Control: Dedicated header sockets for X, Y, and Z axes to control three separate bipolar stepper motors.

• GRBL Firmware Compatible: Seamlessly pair with an Arduino Nano running GRBL to execute standard G-code streams from your computer.

• Configurable Microstepping: Onboard dip-switches/jumper headers allow you to easily adjust the step resolution (up to 1/16 step for A4988 or 1/32 step for DRV8825).

• Versatile I/O Breakouts: Exposed pin headers for essential control features, including Limit Switches, Emergency Stop (E-Stop), I2C communications, and Spindle/Laser enable signals.
