RS-LiDAR-32 User Manual
21
GPS is 3.3V power supply. Also please do not input the power into the +5V pin because the pin is an
output.)
Pin GND provide the ground connection for GPS module.
The GPS module should set to 9600bps baud rate, 8-bit data bit, no parity and 1 stop bit. RS-LiDAR-32
only read the GPRMC message from GPS module., the GPRMC message format is shown as below:
$GPRMC, <1>,<2>,<3>,<4>,<5>,<6>,<7>,<8>,<9>,<10>,<11>,<12>*hh
<1> UTC time
<2> validity - A-ok, V-invalid
<3> Latitude
<4> North/South
<5> Longitude
<6> East/West
<7> Ground Speed
<8> True course
<9> UTC date
<10> Variation
<11> East/West
<12> Mode (A/D/E/N=)
*hh checksum from $ to *
Different GPS module may send out different length GPRMC message, the RS-LiDAR-32 reserve
86-byte space for GPRMC message, so it can be compatible with the majority GPS module in the
market.
