The sensor consists of a 3-axis accelerometer, gyroscope and magnetometer. It can act as an AHRS system. Unlike IMU modules, which only provide raw data, the UM7, using a built-in microcontroller, processes the sensor data using a Kalman filter (EKF) to calculate the position of the headset 500 times per second. This version includes a housing.

We offer two versions of the module,withandwithouthousing.

Power supply to the module and serial communication can be done via a 5-pin connector using the included cable. Two 6-pin connectors provide additional functionality, such as connecting a GPS receiver.


  • High measurement stability
  • Adjustable EKF filter for better performance depending on the application
  • Synchronized data with external GPS module
  • Calibration and compensation of temperature compensation for accelerometer, gyroscope and magnetometer
  • The magnetometer can be configured as soft or hard via the CHR serial software


  • Output:
    • Height - Euler angles
    • Height - attitude quaternion
    • Accelerometer, gyroscope and magnetometer data
    • Altitude, position and speed according to GPS (when external module is connected)
  • UART communication with default speed: 921 600 bps and 3.3 V operating voltage
  • UART interface outputs (RX and TX) tolerate 5 V
  • Transmission uses NMEA (up to 100 Hz), binary packets for high efficiency (up to 255 Hz) or a combination of both modes
  • Flexible communication architecture allows for data transmission in individually adjustable packets
  • Real-time configuration via CHR serial interface software
  • SPI interface via additional connectors


  • Supply voltage: d 4 V to 5.5 V
  • 3.3 V logic (with 5 V tolerance on RX and TX pins)
  • Measurement ranges (configurable):
    • Accelerometer: ± 8 g
    • Gyroscope: ± 2000 °/s
    • Magnetometer: ± 12 gauss
  • Size: 27 x 26 x 6.5 mm
  • Weight: 7,5 g
