The SAM-M8Q GPS with GLONASS, Galileo, QZSS and SBAS receiver technology and built-in micro patch antenna. For your UAV systems, Robots, RC, FPV or other projects.

Features

• 72-channel M8 engine GPS L1C/A, SBAS L1C/A, QZSS L1C/A, QZSS L1 SAIF, GLONASS L1OF, Galileo E1B/C
• High accuracy thanks to concurrent reception of up to 3 GNSS (GPS, Galileo, GLONASS)
• 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
• Built-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 into any design.

Tips

• GPS, GLONASS, SBAS, QZSS are enabled by default
• Blue PPS LED blinking(1Hz) means 3D fixed
• update rate 1Hz & baud rate 9600 default
• Baud 9600~115200 supported by INAV
• update rate 5Hz with INAV Protocol
• update rate 10Hz with INAV Protocol
• BF doesn’t support GPS position hold and RTH, GPS Rescue mode is supported by BF3.5 or last.
• The scratches on the ceramic antenna are the result of tuning the antenna. Placing small nicks in the center of the long edges, or corners brings them into spec.
