Is the equation “Current Limit = VREF × 2.5” for setting the stepping motor current limit also true for the A4988 motor driver if I use VDD =3.3V (from a Raspberry Pi) for the logig voltage of the motor driver ?
If not, wich equation I have to use for the current limit setting of the stepping motor when I use 3.3 V for the motor drive logig (VDD).
