While waiting for motor,chuck,esc... to arrive, i`m thinking about hooking this spindle to arduino (grbl1.1 with pwm variable spindle controll).
Can this item be "in between" esc and arduino? Check it here please:

If this can be used it would be great. By the way...if anyone here control esc with arduino with grbl, let me know, how, please?
