Arduino UNO Shield for GRBL CNC Controller
A custom PCB that goes on top of the Arduino board as a shield, and features four PC817 optocouplers for electrically isolation the CNC machine limit switches from the Arduino board or the Atmega328P microcontroller. Also it features 5mm terminal blocks for easier connecting the CNC machine components to the CNC motion controller.
