IMU: BMI270

Small. Low power. Optimized for wearables.

BMI270

IMU combining accelerometer and gyroscope

The ultra-low power BMI270 is an IMU optimized for wearables providing precise acceleration, angular rate measurement and intelligent on-chip motion-triggered interrupt features.

The 6-axis sensor combines a 16-bit tri-axial gyroscope and a 16-bit tri-axial accelerometer featuring Bosch’s automotive-proven gyroscope technology. BMI270 includes several functionalities such as an integrated plug-and-play step counter/detector for wrist-worn devices. Moreover, the IMU is suitable for hearables, smart clothes, smart shoes, smart glasses and ankle bands.
