Arduino CNC Shield V3 with A4988 / DRV8825 Stepper Motor Driver

Arduino CNC Shield V3 – A4988 / DRV8825 Stepper Motor Driver

Build your own CNC machine, laser engraver, 3D printer, or robotic arm with the Arduino CNC Shield V3. Designed to stack directly onto an Arduino UNO R3, this shield supports up to 4 stepper motor drivers (A4988 or DRV8825) and is fully compatible with GRBL firmware — the industry-standard open-source CNC controller.
