One company has started to make Teensy based sensor boards for NMEA2000. They contacted me due to my library and send me some sample boards. There is one nice ready IMU board. I can ask are they ready to sell.
I'm just about to start a project building a tacho, engine hrs, temp and display it on a Raymarine MFD......(I have a Yanmar)
Unfortunately they are not yet on market.....There is no problem with library to do that except 127252, which is unknown PGN.
PGN 126993 is Heartbeat PGN sent on every 60 sec automatically by the library. This is new required PGN
