Over minutes to hours it dominates heading drift, so a lower value lets a vehicle hold its heading longer between GNSS or vision updates.Can I use UART and SPI at the same time?No. The M-G366PDG supports either UART or SPI, and you connect one of the two.Does it need its own temperature calibration?Epson calibrates bias, scale factor and axis alignment over −40 to +85 °C and stores the parameters in the IMU.

Change the interface or the performance class without redesigning the mounting.Interface1.2 °/h0.8 °/hRS-422M-G552PR1M-G552PR7CANopenM-G552PC1M-G552PC7SAE J1939M-G552PJ1M-G552PJ7FAQFrequently asked questionsWhich variant do I need?Choose the interface your system already speaks, then the performance class. The 1.2 °/h models suit machines with GNSS or odometry aiding; the 0.8 °/h models, such as the M-G552PR7, hold heading longer on their own. The M-G570PR2 is the top model in the same housing.Is the housing really waterproof?Yes, the metal housing is rated IP67 when the mating connector is also IP67. That makes it suitable for outdoor machines, wash-down and marine use.Can I use it with a compact PDG IMU in the same project?Yes. Many customers develop with a compact PDG module on the board and use the M-G552 where the sensor sits outside in the weather.Can I test it before ordering?Yes.
