  • Magnetic Compass QMC5883L
  • Barometer DPS310
  • UART1, Firmware update
  • UART2, onboard GPS
  • UART3, MSP Protocol (To be supported)
  • CAN, UAVCAN Protocol
  • I2C, onboard QMC5883L & DPS310
  • I2C JST-GH connector, external AirSpeed sensor
  • CAN bootloader LED, Blue
    • Fast blinking,  No communication between CAN node and Flight Controllers
    • Slow blinking, Communicating between CAN node and Flight Controllers
  • GPS PPS LED, Green
    • blinking(1Hz) when GPS has 3D fixed
  • Boot button
  • Input voltage range: 4~6V
  • Power consumption: 100mA
  • Operating Temperatures: -20~80 °C
  • 29mm*29mm*9.7mm
  • 11.3g

INCLUDES

  • 1x M8Q-CAN
  • 2x JST-GH-4P to JST-GH-4P 20cm silicon wire

TIPS

  • u-blox M8Q series has no external flash memory
  • Compass Alignment(Arrow forward and flat mounting):
    Ardupilot/Mission Planner: Rotation None
  • 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 by ublox.
  • UART3 MSP Protocol is not implemented for now.
