Modal AI Devs, et.al.,

I'm attempting to add a sensor to the m500 system to ensure level flight of approximately 4 to 5 feet while operating. after reviewing your firmware for the flight core, I noted you have some lidar and range finding sensors.
We currently have a I2C splitter that has both the GPS and range finder attached going into port J10. 
When I connect my aircraft to QGC I cannot get the range sensor to appear in the parameters or the MAVLink inspector. 
reviewing your documentation on the navigation of the m500 system I saw you have GPS and visual navigation pre-configured for the system as default. can I add this range sensor to part of the default system?

Sincerely,
Steve
