Matek Systems M8Q-5883 SAM-M8Q GPS & QMC5883L Compass Module for RC Drone FPV Racing
Specification: Brand name: Matek Item name: GPS & compass module M8Q-5883 Dimensions: L20 x W20 x H10 mm Weight: 7 gram Input voltage range: 4~6V Uart (Tx,Rx) interface for GPS SAM-M8Q I2C (DA,CL) interface for Compass QMC5883L Battery for HOT module start Power LED(Red) & Time pulse LED(Blue) Supported by INAV/Betaflight/Ardupilot, ect.
-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.
-Magnetic sensor QMC5883L integrated
-Max navigation update rate
Single GNSS up to 18 Hz
2 Concurrent GNSS(GPS & GLONASS) up to 10 Hz
-Horizontal position accuracy(GPS & GLONASS) 2.5 m CEP
-Velocity accuracy 0.05m/s
-Cold start 26 s
Aided cold starts: 2 s
Hot start 1 s
-Sensitivity
Tracking & Navigation: –165 dBm
Reacquisition: –158 dBm
Cold start: –146 dBm
Hot start: –155 dBm
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
-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.
