The CNC Shield V4 is designed to operate with the Arduino Nano board. It serves as a driver expansion board for CNC engraving machines and 3D printers. The shield features three dedicated slots for A4988 stepper motor driver modules (drivers not included), allowing control of up to three stepper motors.
Each stepper motor channel requires only two I/O pins, meaning a total of six I/O pins is enough to control all three motors. This makes the CNC Shield V4 a simple and efficient solution for managing multiple stepper motors in your project.
