Navio2 AUXOUT pins

I can’t seem to find the GPIO numbers of pins 13 and 14 on the servo rail. I’m trying to use them as AUXOUT inputs for a range finder but can’t figure out which pin to declare in ardurover. I included screenshots of what I mean. Is it even possible to set these pins as AUXOUT pins like other flight controllers or am I out of luck?

Hi Aryan,

Sorry for the delayed response.

Could you please specify what exact rangefinder you’re using? This might help to see if it’s possible to configure it on Navio2.

Some of our users tested Benewake TFmini connected via UART. You can take a look at Marc’s thread to learn more about it.

trying to use an extremely cheap hc-sr04. Ardupilot rangefinder page has support for it I’m just extremely confused about what auxout pin to select.

You may have to set BRD_PWM_COUNT at 4 in order to use GPIO on pin 13 and 14.

You have also GPIO 17 and 18 available from UART plug.
