Bosch Sensortec BMI570 is a 6-axis inertial measurement unit for wearables and hearables, supporting activity tracking, context recognition, and head orientation/spatial audio. Bosch highlights extended full-scale range, vibration robustness, and a programmable on-sensor Edge-AI classification engine.

Official technical data: soldered-PCB offset ±10 mg (accelerometer) and ±0.5 °/s (gyroscope); temperature offset drift ±0.07 mg/K and ±0.003 °/s/K; sensitivity error 0.1% and 0.3%; typical noise density <50 µg/√Hz (accelerometer, ≤8 g), <60 µg/√Hz (16 g), and <0.003 °/s/√Hz (gyroscope). Typical current: 650 µA at maximum ODR, 250 µA in low-power operation at 100 Hz, and 3 µA in suspend. Includes an 8 KB FIFO; high-performance, normal, low-power, standby, and suspend modes; operating temperature −40 to +85 °C. The public Bosch page does not specify absolute angular accuracy in degrees or an IP protection rating.
