CNC shield V4 needs to work with the 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.
