Double Module Patch Gnss Antenna with U8 GPS&Glonass Module
All serial connections are at 3V CMOS logic levels, if need different voltage levels, use appropriate level shifters.
The baud rate of both serial ports are fully programmable, the data format is however fixed: X, N, 8, 1, i.e. X baud rate,
no parity, eight data bits and one stop bit, no other data formats are supported, LSB is sent first. The modules default
baud rate is set up 9600bps, however, the user can change the default baud rate to any value from 4800 bps to 115kbps.
UART port can be used for firmware upgrade, NMEA output and u solution proprietary commands input.
