UART interface
One channel full-function UART by default can be used for AT communication.
Baud rate: 300bps to 3686400bps. Default rate is 0bps (auto baud rate).
Support auto baud rate, but only limited to 9600, 19200, 38400, 57600 and
115200 bps.
Support RTS/CTS hardware handshake.
DBG_UART can be used for software debug.
GNSS_UART can also be configured as a GNSS NMEA data output port.
USB
USB 2.0 high speed interface.
