Hello
My Pi 5 arrives soon. I just spotted it has a 3 pin JST connector as the console UART. Can it be used as a standard ttl UART? I would like to receive 38400 bps data from rs422 (NMEA183) and it seems that the jst connector would be a handy and robust connection. I read something about setting the baud rate with EEPROM which makes me wonder if there is more to it than the normal Python serial usage. I haven't found much info yet and most of it is about using it with a USB dongle. Does it behave like any other /dev/AMA0 UART. Otherwise I have to hook up TX RX and gnd with individual Dupont connections which is messy and hard to do when it is in a case.
Thanks
