This Arduino motor control shield uses removable A4988 or DRV8825 compatible stepper motor drivers and can be used for engraving machines 3D printers or other applications requiring control of multiple stepper motors, such as for X Y Z control.
Compatible with GRBL 0.8. Open-source firmware operated on Arduino UNO, converting G code commands into stepping signals.
