All of those things have commercial NMEA 2000 sensors that can connect to OpenPlotter, via the USB to CAN adapter.
This short video explains NMEA 2000. I'm not sure why you seem think that OpenPlotter needs sensors connected to it via the RPi GPIO.
Unless there is something else I'm missing. But I don't think I am.
