3D Printer CNC Shield V4 Expansion Board for Nano Board

CNC shield V4 needs to work with the Nano board. It can be used as a drivers expansion board for engraving machines and3D printers. It has in total 3 channel slots forA4988 stepper motor drivermodules (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 CNCshield can make quick work for managing stepper motors in your project.
