arduino cnc shield

the arduino cnc shield is an expansion board designed to work with arduino boards (commonly arduino uno) for controlling cnc machines, laser engravers, and 3d printers. it allows easy connection and control of stepper motors and drivers, enabling precise motion control for x, y, z, and a axes. the shield is widely used in diy automation, engraving, milling, and robotics projects due to its simplicity and compatibility with grbl firmware.

key features

• compatible with popular drivers such as a4988 and drv8825

• adjustable microstepping for precise motor control

• onboard pins for limit switches and control buttons

• easy plug-and-play design for quick installation

• external power supply support for stable motor operation

• compact and durable pcb design

• suitable for cnc machines, laser cutters, and engraving systems
