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
- Build-in embedded GNSS patch antenna, low power consumption
- The 15 x 15 mm patch antenna provides the best compromise between the performance of a Right Hand Circular Polarized (RHCP) antenna and a small size to be integrated in any design.

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
- update rate 5Hz with INAV UBLOX Protocol
- update rate 10Hz with INAV UBLOX7 Protocol
- BF doesn’t support GPS position hold and RTH, GPS Rescue mode is supported by BF3.5 or last.
- The scratches on ceramic antenna are the result of tuning the antenna by ublox. Placing small nicks in the centre of the long edges, or corners, brings them into spec.
