Hey everyone, I am using the motor shield rev3 to drive a DC motor. I am using an external 11V power supply for the motor (jumper cutted) I use a FPGA to generate a 1kHz PWM on a 3.3V GPIO my question is :
Will I benefit from the range of the driver if I supply AREF with a fix 3.3V ? or does the pwm input of the shield needs a 0-5V signal no matter what ?
(no arduino here, just the motor shield)
