3D Printer CNC Shield V4 Expansion Board For Arduino

• Worked with Arduino nano.
• 3 axis stepper motor driver
• Power DC5V interface, 7.5-12V voltage input.
• Compatible with micro-drive laser engraving machine, three-axis CNC engraving machine.
• Easy to connect with other modules and LCD I2C module 

CNC shield V4  works well with the Arduino Nano board. It can be used as a driver’s expansion board for engraving machines and 3D printers. It has in total 3 channel slots for A4988 stepper motor driver modules (not included) for driving 3 channels of stepper motors.

Each channel of stepper motor only needs 2 IO ports, which means 6 IO ports are sufficient to manage 3 stepper motors. This shield can make quick work for managing stepper motors in your project.
