[Matek] 마텍 GPS MODULE SAM-M8Q

Features

• 72-channel 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

• u-blox M8Q series has no external flash memory

• 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.
