How to connect pypilot motor controller to the MacArthur hat? On the motor controller has +3.3V, tx, rx and gnd lines, I try to connect NMEA 0183 data flow. Is this possible at all or need to connect directly to the Rasperry pi?
I can't find any basic instructions anywhere, looks like documentation is before than MacArthur hat entered on market.

You have to connect the pypilot motor controller to UART0 using the Raspberry pin header.
If you use UART0 for pypilot you can not use a MAIANA transponder or a dAISy HAT. If you need UART0 for one of these devices you can also use UART2 in Raspberry 4 (GPIO 0 and GPIO 1) or UART1 in Raspberry 5 (GPIO 0 and GPIO 1) for your pypilot controller.

I think you need dtparam=uart0_console only if you want to use the new three-pin JST-SH connector in RPi5. If you needed that for using UART0 in pypilot, it could be because the pypilot code is not yet updated to RPi5.
