CNC Shield V3 Expansion Board for Arduino Uno (for A4988 / DRV8825 stepper motor drivers)

The CNC Shield V3 expansion board is designed for quick and easy building of CNC machines, mini engravers, laser cutters and 3D printers based on the Arduino Uno microcontroller. The shield has slots for connecting four stepper motor drivers (for example, A4988 or DRV8825), enabling control of the X, Y, Z axes and an additional A axis. The board also features convenient terminals for external power supply (12–36 V), connectors for endstop sensors, spindle control and jumpers for microstepping configuration. Features: Product type: expansion board / CNC shield (CNC Shield Expansion Board) Specifications: V3 version, slots for 4 stepper motor drivers (X, Y, Z, A axes), 12–36 V power terminal block, connectors for endstop switches and spindle Purpose: assembly and control of CNC machines, engravers, plotters and 3D printers
