BNO055 Intelligent 9-Axis Sensor

The BNO055 Intelligent 9-Axis Sensor is an innovative sensor that combines multiple functions in a compact module. It integrates a 14-bit accelerometer, a 16-bit gyroscope sensor, and a geomagnetic sensor, which work together with an integrated 32-bit microcontroller. This "system-in-package" design allows you to implement high-precision motion and orientation measurements in your projects. Thanks to intelligent sensor fusion, the sensor can directly provide complex data such as quaternions, Euler angles, and rotational vectors without requiring additional processing. The sensor supports both I2C and SPI communication and is compatible with operating voltages from 3.3 V to 5.5 V. With its small dimensions of 19 x 21 mm, it is ideal for portable 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 integrate it effortlessly into your projects.
