• Firmware: AP_Periph MatekG474-GPS
• Firmware can be updated via G474 DFU mode

• M9N-G4-3100 is based on ArudPilots’ AP_Periph firmware,  It is a GNSS+COMPASS peripheral with CAN/DroneCAN and UART/MSP interfaces.
• M9N-G4-3100 uses multi-constellation GNSS powered by M9 series , It 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.
• M9N-G4-3100 integrates an industrial-grade compass PNI RM3100 which provides high resolution, low power consumption, no hysteresis, large dynamic range, and high sampling rates.
• G474 CAN node is compatible with CAN FD(5 Mbps) & CAN 2.0 (1 Mbps)

Tips & Notes

• on M9N-G4-3100, The 3 magnetic coils have little solder paste to avoid the excess to “tilt” them, resulting in some reading inaccuracies of the compass. Any strong impacts will definitely separate them, especially the “tall coil” Sen-Z-f.  Pls use this precision module with care.
• Start with ubx GNSS FW3.01, timepulse is aligned with UTC time and that time is set valid only after leap second is downloaded. That could take up to 12.5 min. Probably PPS LED will not blink immediately after GPS has 3D fixed.
• The M9N-G4-3100 provides the ability to reset the receiver. Bridging “M9N-RST” pad to Ground for at least 100 ms will trigger a cold start. RESET will delete all information and trigger a cold start. It should only be used as a recovery option.
• No barometer integrated.
