The BNO055 is the first in a new family of Application Specific Sensor Nodes (ASSN) implementing an intelligent 9-axis Absolute Orientation Sensor, which includes sensors and sensor fusion in a single package.

Bosch is the first company to combine MEMS accelerometer, magnetometer and gyroscope and putting them on a single die with a high speed ARM Cortex-M0 based processor to digest all the sensor data, abstract the sensor fusion and real time requirements away, and provide output data you can use in quaternions, Euler angles or vectors.

The BNO055 is a System in Package (SiP), integrating a triaxial 14-bit accelerometer, a triaxial 16-bit gyroscope with a range of ±2000 degrees per second, a triaxial geomagnetic sensor and a 32-bit microcontroller running the company’s BSX3.0 FusionLib software. At just 5.2 x 3.8 x 1.1 mm³, it is significantly smaller than comparable discrete or system-on-board solutions.

By integrating sensors and sensor fusion in a single device, the BNO055 eases the integration process for customers, freeing them from the complexities of multivendor solutions so they can spend more time on product innovation, including novel applications such as wearable hardware. It is also the perfect choice for augmented reality, more immersive gaming, personal health and fitness, indoor navigation and any other application requiring context awareness.

This sensor data can be used with I2C and UART interface.

I2C Address: I2C 7-bit address = 0x28 (default) or 0x29

The BNO055 can output the following sensor data:

• Absolute Orientation (Euler Vector, 100Hz) Three axis orientation data based on a 360° sphere
• Absolute Orientation (Quaterion, 100Hz) Four point quaternion output for more accurate data manipulation
• Angular Velocity Vector (100Hz) Three axis of 'rotation speed' in rad/s
• Acceleration Vector (100Hz) Three axis of acceleration (gravity + linear motion) in m/s^2
• Magnetic Field Strength Vector (20Hz) Three axis of magnetic field sensing in micro Tesla (uT)
• Linear Acceleration Vector (100Hz) Three axis of linear acceleration data (acceleration minus gravity) in m/s^2
• Gravity Vector (100Hz) Three axis of gravitational acceleration (minus any movement) in m/s^2
• Temperature (1Hz) Ambient temperature in degrees celsius
