The Boardoza BNO055 Breakout Board is an advanced 9-axis absolute orientation sensor that combines a triaxial 14-bit accelerometer, a triaxial 16-bit gyroscope with a range of ±2000 degrees per second, and a triaxial geomagnetic sensor. This integration provides accurate and reliable orientation data for applications such as robotics, augmented reality, gaming, and personal navigation.
This module operates with 3.3V or 5V, ensuring compatibility with a wide range of microcontrollers. By default, it communicates via I2C, but can be configured to UART mode using the PS0 and PS1 pins. The PS0, PS1, INT, and ADR pins operate at 3.3V, facilitating seamless interfacing with low-power MCUs.
