5.4 USB interface
A USB interface, which is compatible to USB version 2.0 FS (Full Speed, 12 Mbit/s), can be used for
communication to a host. The VDD_USB pin supplies the USB interface.
5.5 Default interface settings
Interface Settings
UART 38400 Baud, 8 bits, no parity bit, 1 stop bit.
Output messages: NMEA GGA, GLL, GSA, GSV, RMC, VTG, TXT (no UBX).
Input protocols: UBX, NMEA and RTCM 3.3.
USB Output messages activated as in UART. Input protocols available as in UART.
I2C Output messages activated as in UART. Input protocols available as in UART.
SPI Output messages activated as in UART. Input protocols available as in UART.
Table 18: Default interface settings
Refer to the u-blox NEO-M9N Interface description [2] for information about further
settings.
By default the NEO-M9N outputs NMEA 4.10 messages that include satellite data for all GNSS
bands being received. This results in a higher-than-before NMEA load output for each navigation
period. Make sure the UART baud rate being used is sufficient for the selected navigation rate and
the number of GNSS signals being received.
