It has in total 3 channel slots for a4988 stepper motor driver modules not included for driving 3 channel of stepper motors. If you want to set micro stepping as they are you can t. Open the file and you should see as shown or similar in the screenshot.
The pins that set the micro step mode on the driver are already pulled down to gnd internally as default and to change there state they.
Cnc shield v4 0 has some gpio of arduino nano it s convenient for connect other modules like limit switch. Or is it in theory yes and in practice with enough time too but this board seem to. Keyestudio cnc shield v4 0 needs to work with keyestudio nano ch340. Who ever cloned made this shield made a mistake and put the pins that should go to vcc to gnd.
