Hi, I have just find out this thread. That sounds promising. I have not read all posts, I need some free time 
but here are my first thoughts.
- It would be perfect that you could use the current software features of Openplotter so you do not need to program anything.
- Please make this compatible with moitessier hat and pypilot!!
- I think RPi can not manage multiple EEPROMs and moitessier hat has already one.
- We do not need RTC.
- N2K is ok but instead of NMEA 0183 in/out I prefer to have digital and analog sensors. NMEA 0183 could be connected by USB with cheap converters.
Moitessier hat uses SPI (CS0) and I2C. Pypilot uses UART and makes an intensive use of I2C (IMU). I think you have many I2C devices and this could be too much for the poor raspberry I2C interface.
