    BMI270

    BMI270 is an ultra-low power IMU optimized for wearable applications. The IMU combines precise acceleration and angular rate measurement with intelligent on-chip motion-triggered interrupt features. The 6-axis sensor combines a 16-bit triaxial gyroscope and a 16-bit triaxial accelerometer in a compact 2.5 x 3.0 x 0.8 mm³ LGA package.

    The BMI270 is a member of Bosch Sensortec’s BMI260 family of IMUs, targeting fast and accurate inertial sensing in wearable applications. BMI270 features Bosch’s automotive-proven gyroscope technology with an improved accelerometer. Significant improvements in BMI270 include, but are not restricted to, the overall accelerometer performance, i.e. an extremely low zero-g offset and sensitivity error, low temperature drifts, robustness over PCB strain and a low noise density.

    BMI270 features the industry’s first self-calibrating gyroscope using motionless CRT (Component Re-Trimming) functionality to compensate MEMS typical soldering drifts, ensuring post-soldering sensitivity errors down to ± 0.4%.

    Bosch Sensortec's BMI270 includes intuitive gesture, context and activity recognition with an integrated plug-and-play step counter/detector, which is optimized for accurate step counting in wrist-worn devices. The IMU is also well suited for other types of wearable devices, such as hearables, smart clothes, smart shoes, smart glasses and ankle bands.
