BNO08X family

The BNO08X family is a 9-axis sensor hub that combines an accelerometer, gyroscope, and magnetometer with onboard sensor-fusion firmware. It can output raw sensor data as well as fused signals such as gravity, linear acceleration, and quaternion-based orientation reports.

Overview

DepthAI-exposed runtime behavior

DepthAI runtime behavior is not always identical to the sensor's native silicon capability. Luxonis public IMU documentation distinguishes between max supported report rates, stable operating rates, and rate-rounding behavior for BNO08X.
SpecValue
Stable accelerometer request points15 / 31 / 62 / 125 / 250 / 500 Hz
Stable gyroscope request points25 / 33 / 50 / 100 / 200 / 400 Hz
Raw gyro max exposed rateup to 1000 Hz
Accelerometer max exposed rateup to 512 Hz
Rotation vector max exposed rateup to 400 Hz
Rate rounding behaviorRequested rate rounds up to the next supported rate
