Features
72-channel u-blox M8 engine GPS L1C/A, SBAS L1C/A, QZSS L1C/A, QZSS L1 SAIF, GLONASS L1OF, Galileo E1B/C
On-board Ultra low noise 3.3V voltage regulator and RF filter for noise blocking
Features an additional front-end LNA for optimized performance and a front-end SAW filter for increased jamming immunity

Tips
GPS, GLONASS, SBAS, QZSS are enabled by default
Blue PPS LED blinking(1Hz) means 3D fixed
update rate 1Hz & baudrate 9600 default
Baud 9600~115200 supported by INAV/BF/Ardupilot
update rate 5Hz with INAV UBLOX Protocol
update rate 10Hz with INAV UBLOX7 Protocol
Compass Alignment(Arrow forward):
INAV/BF: CW 270° Flip
Ardupilot/Mission Planner: Rotation None
BF doesn’t support GPS position hold and RTH,  GPS Rescue mode is supported by BF3.5 or last.
No need compass for Fixed wings with INAV firmware
The scratches on ceramic antenna are the result of tuning the antenna by ublox.
