CNC Shield A4988 Arduino for 3D Printers and Milling Machines (GRBL)

This shield is perfect for building a CNC machine! But you can also use it for other mechanical Arduino projects where you want to control up to four stepper motors. The appropriate A4988 stepper motor drivers need to be plugged onto the shield (A4988 not included in delivery). Please note the pin assignment when plugging in the A4988 drivers. The Enable Pin is marked with EN on the board. The board can be operated with an Arduino UNO and the GRBL Open Source (G-Code Control) software.
If you want to operate the stepper motors with microsteps, you still need 3 jumpers (jumpers not included in the delivery) per axis to set 1/16 steps.
