Hello everybody ....this is my first post herer so I don't know if I'm writing it the right way
The arduino Due has a maximum output voltage of 3.3V.....that's what I understood..... my question is if I want to control a DC motor with L298P  by sending PWM signals.... if I sent (255)does it run on full speed or because the maximum voltage is 3.3 it won't ??
and any ideas how to make it run on full speed ??

It should run fine because a quick look at the datasheet reveals that VIH is 2.3V, so 3.3V logic from the Due is compatible with the driver inputs.
