Introduction
Note: Unfortunately the BNO080 is EOL. For users looking for a replacement, try checking out the Qwiic VR IMU Breakout (BNO086) that is available as a drop-in replacement. There are also a few additional features available for the BNO086. For more information, check out the
SparkFun VR IMU Breakout - BNO086 (Qwiic) Hookup Guide.
Bosch's BNO080 is a combination triple axis accelerometer/gyro/magnetometer packaged with an ARM Cortex M0+ running powerful algorithms. The BNO080 Inertial Measurement Unit (IMU) produces accurate rotation vector headings, excellently suited for VR and other heading applications with a static rotation error of 2 degrees or less. It’s what we’ve been waiting for: all the sensor data is combined and drift corrected into meaningful, accurate IMU information. It's perfect for any project that needs to sense orientation or motion. We've taken this IMU and stuck it on a Qwiic enabled breakout board, in order to make interfacing with the tiny, QFN package a bit easier to connect.

In this hookup guide, we'll connect our sensor up to our microcontroller of choice and separately read the rotation vectors (which is what we will mainly want), acceleration vectors, gyro values, and magnetometer vectors. We'll check out how to implement the step counter on the BNO080 in order to use it as a pedometer. We'll also read Q values and various other metadata from the sensor. Knowing what activity you're performing is important so we'll learn how to classify what activity the IMU is performing (i.e. Sitting still, moving, biking, walking, running, etc...) and how confident the IMU is that each activity is being performed. The examples will also show how to calibrate our hardware to give us the most accurate readings possible. Printing out raw packets will also be examined for debugging purposes. Finally, we'll examine how to configure the sensor on different I2C ports and addresses. A bonus example is provided in Processing to show us how to use quaternion data to orient a cube.
