Adafruit BNO055 9-DOF Absolute Orientation IMU Breakout - STEMMA QT

Overview

Adafruit BNO055 9-DOF IMU Absolute Orientation Breakout is a compact orientation sensor board built around Bosch's BNO055, which combines a triaxial accelerometer, gyroscope, and magnetometer with an onboard ARM Cortex-M0 running sensor-fusion firmware. Instead of processing raw 9-axis data on your microcontroller, you can read ready-to-use orientation and motion data directly over I2C.

This STEMMA QT version keeps the same core functionality as the standard breakout, but adds compact board sizing and dual STEMMA QT / Qwiic-compatible connectors for fast solderless hookup. It can output Euler angles, quaternions, angular velocity, acceleration, linear acceleration, gravity vector, magnetic field, and temperature, making it useful for robotics, motion tracking, balancing projects, wearables, and interactive builds.

The breakout is designed for 3V or 5V logic-safe systems and accepts 3.3V to 5.0V on VIN. It also breaks out extra interrupt and control pins and includes address selection so you can place two BNO055 sensors on one I2C bus. Note that the BNO055 has known I2C compatibility limitations with some chip families and I2C multiplexers, so it is best paired with hosts such as SAMD51, RP2040, STM32F4, or nRF52840 where operation is generally more reliable.
