Description The Holybro DroneCAN GPS has a u-blox M8N or M9N module, BMM150 compass, and tri-colored LED indicator. It has the STM32G4 Processor and adopts the DroneCAN protocol for communication, making it more reliable and better at dealing with electromagnetic interference compared to a 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. Current and future batch now support software toggle for CAN termination resistance Specification: DroneCAN M9N 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 Flight Controller FW PX4, Ardupilot Port Type GHR-04V-S Antenna 25 x 25 x 4 mm ceramic patch antenna Antenna Gain 1.5dbi Antenna LNA Gain 22dB 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 27cm Other Notes - LNA MAX2659ELT+ RF Amplifier- Rechargeable Farah capacitance- Low-noise 3.3V regulator For other technical information, please go to https://docs.holybro.com/ DroneCAN 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.
