This BN0055 sensor hub integrates a variety of sensors. Includes: a 3-axis 12-bit accelerometer, a 3-axis geomagnetic sensor, and a 3-axis 16-bit gyroscope, plus a built-in 32-bit MCU to handle software calculations between different sensors. It's a compact sensor hub supporting Windows 8.1. Provides individual data from the three sensor types (acceleration/geomagnetic/gyroscope) or combined data. Built-in MCU calculation offers broader application support for products like smartphones and wearables.
