This is why we use UART3 for NMEA 0183-1 and UART3 for NMEA 0183-2.
Same for NMEA 2000, we use SPI0-1 instead of SPI0-0 which is used by lot of HATs and devices.
Ok - this makes Sense for me:
- Optional GPS reception and AIS reception/transmission with the MAIANA AIS base kit. The MacArthur HAT has all the features of all MAIANA AIS adapters in one. Data connection by UART0.
Lets hope the needed RPI´s 4 for multipe UARTS get in Stock again soon.
