BMI261

IMU combining accelerometer and gyroscope

The ultra-low power BMI261 is a 6-axis IMU featuring a 16 bit tri-axial gyroscope and accelerometer specifically designed for Android™ operation systems. Fully HiFi compliant, this sensor is optimized for always-on smartphone gesture and activity recognition. Combining precise acceleration, angular rate measurement and intelligent on-chip motion-triggered interrupts, the BMI261 offers Bosch’s automotive-proven gyroscope technology, highly accurate step counting, motion detection and is pin-to-pin compatible with the BMI160.
