Introduction

BNO055 is a new sensor IC for implementing an intelligent 9-axis Absolute Orientation Sensor. It is a System in Package, integrating a triaxial 14-bit accelerometer, a triaxial 16-bit gyroscope, a triaxial geomagnetic sensor, and a 32-bit microcontroller.

With a size of 5.2 x 3.8 x 1.1mm, the BNO055 is significantly smaller than comparable discrete or system-on-board solutions and also is the sensor-hub product of the smallest size that supports Windows 8.1 at present.

BNO055 is able to provide not only single data of the three kinds of sensors (accelerometer/gyroscope/geomagnetic), but also integrated data, such as quaternions, Euler angles, or vectors. Besides, the built-in MCU frees the users from the complexities of algorithm processing, which provides application support in many aspects for smartphones, wearable devices, and so on.
