I'm trying to spy on the state of servo communications with a RC receiver and optionally change the output. Unfortunately my controller is 3.3v while the servo logic is ~5v. I'm trying to figure out what the easiest way of doing this is.
The circuit I've come up with is as follows: reciever -> translator -> mux (translator/controller) -> translator -> servo
Does this make sense and will it maintain a reasonable level of signal integrity?
I know the Ardupilot does something similar but as far as I can tell, the whole device operates on 5v so no logic level shifting is needed
