BNO055 Intelligent 9-Axis Sensor

The BNO055 Intelligent 9-Axis Sensor is an innovative sensor that combines multiple functions into a compact module. It integrates a 14-bit accelerometer, a 16-bit gyroscope sensor, and a geomagnetic sensor, all working in conjunction with an integrated 32-bit microcontroller. This «system-in-package» design allows you to implement highly accurate motion and orientation measurements in your projects. Thanks to the intelligent sensor fusion, the sensor can directly provide complex data such as quaternions, Euler angles, and rotation vectors without requiring additional processing. The sensor supports both I2C and SPI communication and is compatible with operating voltages from 3.3V to 5.5V. With its small dimensions of 19 x 21 mm, it is ideal for wearable devices, robotic controls, and smart applications. It also offers various power-saving modes and is designed to operate efficiently in mobile and battery-powered systems. The sensor is easy to mount and is supported by comprehensive libraries, allowing you to quickly integrate it into your projects.
