Matek GPS & Compass M8Q-CAN, UAVCAN

This GPS was designed around ArduPilot supporting UAVCAN bus such as the Matek H743 Wing. It has onboard SAM-M8Q, compass, and barometer.

Specifications:

• ArduPilot AP_Periph F303 CAN node
• GPS SAM-M8Q (GPS, GLONASS, Galileo)
• 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.

Wiring and AP Parameters:

*** You must set CAN Node parameters for airspeed sensor connected to I2C port of M8Q-CAN ***

Mission Planner > Initial Setup > Optional Hardware > UAVCAN >  SLCan Mode CAN1  > Parameters

• MS4525   ARSP_TYPE -> 4
• MS5525   ARSP_TYPE -> 3
• SDP3X     ARSP_TYPE -> 6
• DLVR-L10D    ARSP_TYPE -> 9 (default in hwdef)
• Write and reboot

MSP Parameters:

ArduPilot (latest firmware after Sep.09)

• Serialx_PROTOCOL  = 32  (MSP) where x is the SERIAL port used for connection on autopilot.
• GPS TYPE = 19 (MSP)
• GND_PROBE_EXT  = 4096  (MSP Baro)
• GND_PRIMARY = 1  (If you want to use MSP baro as primary baro, otherwise leave as default)
• COMPASS_TYPEMASK  0   (make sure MSP bit is not checked)

INAV  (since 2.6)

• In ports tab, Enable MSP on corresponding UART that M8Q-CAN connected
• feature GPS
• set gps_provider = MSP
• set mag_hardware = MSP
• set baro_hardware = MSP
