Default RIOT shell access utilize XDS110 debug probe integrated with launchpad board.
It provides virtual serials via USB interface - for connecting to RIOT shell, use
the first one.
If a physical connection to UART is needed, disconnect jumpers RXD and TXD joining
cc1352 microcontroller with XDS110 and connect UART to pin RXD/DIO12 and TXD/DIO13.
The default baud rate is 115 200 - in both connection types.
@warning Launchpad cc1352 board is not 5V tolerant. Use voltage divider or logic
level shifter when connecting to 5V UART.
