UART connection to Pi3B+

[MuchD0ge]

The MCU section in the setup guide for UART communication does not work on a Pi3B+ (can't test other boards)
and should include like this for possible troubleshooting:

[mcu]
serial: /dev/ttyS0
serial: /dev/ttyAMA0
restart_method: command

The MCU connections can be seen through kiauh under advanced>Get MCU ID>UART
Which results in the following list:

The MCU communicates over two UART connections, at least in my case.
I have found a few other people having the same issue, so it might be worthwhile to include in the guide.

thanks to u/boanerges57 on reddit for leading me down this path.
