CNC Motor Drive Expansion Shield for Arduino

The CNC motor drive expansion shield is designed to interface stepper motors and motor drivers with Arduino boards for CNC and motion control applications.
It provides independent channels for controlling multiple stepper motors, including direction and pulse signal management.
The shield is compatible with standard Arduino headers and can be stacked directly onto Arduino boards.
It supports easy integration with CNC control software and stepper driver modules.
Typical applications include CNC routers, 3D printers, and automated positioning systems.
