    BMI261

    BMI261 is an ultra-low power IMU especially designed for the Android™ ecosystem and is therefore fully HiFi compliant. The IMU combines precise acceleration and angular rate measurement with intelligent on-chip motion-triggered interrupts. The 6-axis sensor features a 16-bit triaxial gyroscope and accelerometer in a compact 2.5 x 3.0 x 0.8 mm³ LGA package.

    BMI261 is a part of the BMI260 family and is optimized for always-on smartphone gesture and activity recognition. BMI261 is fully compliant to Android operating systems. BMI261 provides highly accurate step counting, motion detection and is pin-to-pin compatible with the BMI160. BMI261 features Bosch’s automotive-proven gyroscope technology. Significant improvements in BMI261 include extremely low zero-g offset and sensitivity error, low temperature drifts, robustness over PCB strain and a low noise density.

    On top, BMI261 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%.

    Applications

    - Advanced gesture / activity and context recognition

    - Optical and electronic image stabilization (OIS/EIS)

    - Simultaneous localization and mapping (SLAM)

    - Location based services

    - Augmented / virtual reality (AR/VR)

    - Indoor navigation / pedestrian dead reckoning (PDR)

     
     

    Mobile Applications

    BMI261 is designed for best fit into modern Android™ smartphones and provides a primary digital interface (I2C and SPI) and a freely configurable secondary digital interface (I2C and SPI). Dual SPI configuration enables BMI261 to serve two SPI-based modules supporting stereo or 3D camera operation

    Imaging Applications

    The new BMI260 family boasts powerful OIS and EIS features. BMI261’s low latency, minimal group delays and high-precision time stamps on µs level substantially improve photo/video quality in the context of optical and electronic image stabilisation (OIS/EIS). Using BMI261 on the mainboard in dual interface operation mode enables congruent HMI and OIS functions, such as stabilized panorama photo panning and action video tagging.
