Matek Systems GNSS M9N-5883 NEO-M9N GPS Module With Magnetic Compass QMC5883L Support GLONASS, Galileo for FPV RC Racing Drone Precise details: M9N-5883 uses multi-constellation GNSS powered by u-blox NEO-M9N , NEO-M9N is a concurrent GNSS receiver which can receive and track multiple GNSS systems. Owing to the multi-band RF front-end architecture all four major GNSS constellations, GPS,Galileo, GLONASS and BeiDou can be received concurrently. More details about the NEO-M9N, pls check out u-blox NEO-M9N page -Description: Brand: Matek Systems GNSS u-blox NEO-M9N (GPS, GLONASS, Galileo and BeiDou) Magnetic Compass QMC5883L Patch antenna 25*25*4mm Input voltage range: 4~6V (5V pad/pin) Power consumption: 50mA Operating Temperatures: -20~80 °C UART(TX, RX) interface for GNSS NEO-M9N I2C(DA, CL) interface for Compass QMC5883L JST-GH-6P connector 3.3V Power LED, Red GNSS PPS LED, Green, blinking(1Hz) when GNSS has 3D fixed 32mm*32mm*10mm 14.5g -Wiring and settings * M9N-5883 5V to Flight controller 4~6V * M9N-5883 RX to Flight controller UART_TX * M9N-5883 TX to Flight controller UART_RX * M9N-5883 CL to Flight controller I2C_SCL * M9N-5883 DA to Flight controller I2C_SDA * M9N-5883 G to Flight controller GND * Compass Alignment(Arrow forward and flat mounting): INAV/BetaFLight: CW 270° Flip when flight controller arrow is facing forward also Ardupilot/Mission Planner: Rotation None * Protocol: Ublox or NEMA * Make sure to have compass/magnetometer 10cm away from power lines/ESC/motors/iron based material * The scratches on ceramic antenna are the result of tuning the antenna. * u-center Windows -Tips ArduPilot supports NEO-M9N well INAV2.5 ublox/ublox7/NEMA all don´t support NEO-M9N for now. new protocol is required in INAV2.6 Betaflight UBLOX protocol doesn´t support NEO-M9N, Pls select NEMA protocol & Auto Baud. -Mateksys GNSS M9N-5883 Specification SKU:M9N-5883 ublox:NEO-M9N GNSS:GPS/BeiDou/GLONASS/Galileo around 30 Sats Position accuracy:2.0m CEP Tracking and nav.:-167 dBm Reacquisition:-160 dBm Cold start:-148 dBm Hot start:-159 dBm Nav. update rate:25Hz Compass:QMC5883L Barometer: / Interface:UART+I2C 6Wires CAN Node: / Size:32*32*10mm Weight:14.5g -Package included: 1x M9N-5883 1x JST-GH-6P to JST-GH-6P 20cm silicon wire
