If you've ever ordered and wire up a 9DOF sensor, chances are you've also realized the challenge of turning the sensor data from an accelerometer, gyroscope and magnetometer into actual "3D space orientation"! Orientation is a hard problem to solve. The sensor fusion algorithms (the secret sauce that blends accelerometer, magnetometer and gyroscope data into stable threeaxis orientation output) can be mindnumbingly difficult to get right and implement on low cost real time systems.
Bosch is the first company to get this right by taking a MEMS accelerometer, magnetometer and gyroscope and putting them on a single die with a high speed ARM CortexM0 based processor to digest all the sensor data, abstract the sensor fusion and real time requirements away, and spit out data you can use in quaternions, Euler angles or vectors.
The new version of the board includes SparkFun qwiic compatible STEMMA QT connectors for the I2C bus so you don't even need to solder! Use a a plugandplay STEMMA QT cable to get 9 DoF data ASAP.
Rather than spending weeks or months fiddling with algorithms of varying accuracy and complexity, you can have meaningful sensor data in minutes thanks to the BNO055  a smart 9DOF sensor that does the sensor fusion all on its own!
