V4 Expansion Board CNC Shield Stepper Motor Driver Board For Arduino Nano

CNC shield V4 needs to work with Arduino Nano. It can be used as Driver 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 the stepper motor only needs 2 IO ports, which means 6 IO ports are sufficient to manage 3 stepper motors. This Breakout shield can make quick work for managing stepper motors in your project
