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.

Jargon buster
Plain-language definitions for the technical terms used above.
- Gyroscope
- A gyroscope measures rotation, such as how fast a board is turning around its X, Y, and Z axes. This matters for projects like gesture controls, balancing robots, and motion tracking where tilt or rotation changes need to be detected.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- I2C address
- An I2C address is the number a device uses so a microcontroller can tell it apart from other devices on the same I2C bus. It matters because two devices with the same fixed address may conflict if used together.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
