CNC Shield V3 for Arduino – 4-Axis Stepper Motor Driver Board
CNC Shield V3 – 4-Axis Stepper Motor Driver Expansion Board for Arduino
The CNC Shield V3 is an expansion board for Arduino Uno that enables precise control of up to four stepper motors. It is widely used in DIY CNC routers, 3D printers, laser engravers, and other motion control projects. This shield accepts A4988 or DRV8825 stepper motor driver modules, allowing microstepping control for smooth and accurate movement.

Compatibility
This shield is designed to stack directly onto an Arduino Uno R3. It is compatible with GRBL firmware, which converts G-code into stepper motor pulses. It works with most A4988 and DRV8825 driver modules, supporting a wide range of NEMA 17 stepper motors. For higher current motors, consider active cooling.
Wiring Notes
Always disconnect power before inserting or removing driver modules. The motor power terminals accept 12-36V DC; ensure your power supply can handle the total current draw. The shield includes jumpers for microstepping configuration—refer to your driver’s datasheet for correct settings.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Mega?
No, the CNC Shield V3 is designed for Arduino Uno R3 layout. For Mega, you would need a different shield or adapter.
Can I use it without GRBL?
Yes, you can write custom Arduino sketches to control the stepper motors directly using the AccelStepper library or similar. However, GRBL simplifies G-code based control.
Does it come with stepper drivers?
No, this is just the shield. You will need to purchase A4988 or DRV8825 driver modules separately. We recommend at least 3 drivers for a basic 3-axis CNC setup.
