Overview: The Holybro DroneCAN GPS has an UBLOX M8N or M9N module, BMM150 compass, tri-colored LED indicator. It has the STM32G4 Processor and adopted the DroneCAN protocol for communication, making it more reliable and better in dealing with electromagnetic interference compare to serial connection. It does not occupy any serial port of the flight controller, and different CAN devices can be connected to the same CAN bus via a CAN splitter board. Specification: GNSS Receiver Ublox NEO M9N Number of Concurrent GNSS Up to 4 GNSS (GPS, Galileo, GLONASS, BeiDou) Processor STM32G4 (170MHz, 512K FLASH) Compass BMM150 or IST8310 Frequency Band GPS: L1C/A GLONASS: L10F Beidou: B1I Galileo: E1B/C GNSS Augmentation System SBAS: WAAS, EGNOS, MSAS, QZSS Navigation Update 5Hz Default(10Hz MAX) Accuracy 2.5m Speed Accuracy 0.05 m/s Max # of Satellites 22+ Communication Protocol DroneCAN @ 1 Mbit/s Supports Autopilot FW PX4, Ardupilot Port Type GHR-04V-S Antenna 25 x 25 x 4 mm ceramic patch antenna Power consumption Less than 200mA @ 5V Voltage 4.7-5.2V Operating Temperature -40~80℃ Size Diameter: 54mm Thickness: 14.5mm Weight 36g Cable Length 26cm Other Notes - LNA MAX2659ELT+ RF Amplifier- Rechargeable Farah capacitance- Low noise 3.3V regulator DroneCAN M9N DroneCAN is the primary CAN protocol used by the ArduPilot and PX4 projects for communication with CAN peripherals. It is an open protocol with open communication, specification and multiple open implementations.
