Learnings something new every day :-)
So you've bought the $500 kit including DR module? What about the Murata gyro in your thread? Is that the part included in the kit? Getting confused on a higher level...
One way forward would be to get a
EVK-5H-0 kit and build a small cpu system that takes the NMEA info from it and together with a gyro signal, tacho and direction and a clever algoritm generates standard NMEA traffic when there is no signal.
If there was such a thing as a USB gyro that algoritm could even run on the carputer.
Maybe its that USB device I should build? Algoritms available?
