CNC Shield V3 Bundle with 4 pieces A4988 stepper driver with heat sink for 3D printer compatible with Arduino

The A4988 stepper motor drivers have to be plugged on the shield. When plugging in the A4988 drivers, pay attention to the pinout. The enable pin is marked with EN on the board. The board can be operated with GRBL open source (G-code control) software.

If you want to run the stepper motors with microsteps, you still need 3 jumpers per axis to set 1/16 steps.
