    Hi,

    I'm trying to power the arduino by this motor driver but I keep getting zero Volts in VOut port nor VDD port.

    How do I enable it? Could you help me?

    Thanks,

    Hi,

    I have the previously version of this driver.

    My question is about the PWM interpretation behavior of this driver.

    I've tested to send some PWM fractions to see the output Voltage behavior.

    It was not linear.

    I had a LiPo 11,7 volts battery connected. However, to get 6V output signal, I had to send a PWM signal of 50 (max. 255).

    My doubt is, was it supposed to have a linear behavior? I mean, to get aprox. 6V, send a PWM of 255/2.

    The second question is: How do I set the driver to provide 5V output to power the Arduino? I saw here I just have to put the jumper in. It didn't work.

    Thanks!! Your products are very good, by the way.
