Features
- 72-channel UBLOX 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
- Additional front-end LNA for optimized performance and a front-end SAW filter for increased jamming immunity
- Build-in embedded GNSS patch antenna, low power consumption
- The 15mm / 15mm patch antenna provides the best compromise between the performance of an RHCP antenna and a small size to be integrated in any design.
- Magnetic sensor QMC5883L integrated

Notes
- GPS, GLONASS, SBAS, QZSS are enabled by default
- Blue PPS LED blinking (1Hz) means 3D is fixed
- Update rate of 1Hz & baudrate of 9600 are default
- Baud 9600 - 115200 are supported by INAV/BF/Ardupilot
- Update rate of 5Hz with INAV UBLOX Protocol
- Update rate of 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.
