Product Details
Adafruit 9-DOF Orientation IMU Fusion Breakout - BNO085 (BNO080) - STEMMA QT / Qwiic
The Adafruit BNO085/BNO080 IMU Fusion Breakout is a next-generation solution for precise, low-latency motion sensing. Unlike raw IMU sensors that require intensive microcontroller calculations, the BNO085 features a dedicated fusion coprocessor that runs advanced algorithms (from Hillcrest Labs' SH-2 core). This onboard processing transforms raw sensor data from the accelerometer, gyroscope, and magnetometer into highly accurate, stable, and ready-to-use orientation data.
This module provides outputs in sophisticated formats like Quaternions and Euler Angles, offering a reliable "9 Degrees of Freedom" tracking capability. The inclusion of the STEMMA QT / Qwiic connector makes integration remarkably easy and solderless with compatible development boards like Arduino, ESP32, and Raspberry Pi. It automatically handles the complex task of drift correction and sensor calibration, making it the perfect choice for demanding applications such as virtual reality (VR) tracking, drone navigation, and high-fidelity motion analysis.
