Description CNC Expansion Board V3 Engraver 3D Printer CNC Shield Expansion Board A4988 Driver For Arduino UNO
CNC Shield v3.0 expansion board for Arduino UNO.
Based on it, you can create CNC (CNC machine tools):
3D printer;
engraving router;
Milling router;
laser router.
The expansion board can work with A4988 or DRV8825 motor drivers using GRBL firmware.
Board Specifications:
