Hi,

I'd like to hook up a Monster Moto board to an ESP32 Thing, but I'm not sure about the logic voltage, will it work off 3.3? I notice that the 5v supply pin on the shield is used, and plugs into the the 5v supply on an arduino.

Let us say that pad needs to be supplied with 5v, it's doable in my application, but what about the PWM and Direction control inputs, can they be 3.3v?

Apologies if this is a stupid question, I did try to google the answer first ....

thanks,
Kevin.
