, the motion sensor you were looking for: that just gives you the directly usable information without requiring you to first consult with a to learn the arcane arts of Sensor Fusion. The BNO085 takes the life's work of multiple people who have spent their entire career focused on how to get useful information from direct motion sensor measurements and then squeezes that information down into a 5.2x3.8mm box, along with the sensors to go along with it. Please note, the BNO085 is the "upgrade fix" to BNO080 - it is completely back-compatible with the BNO-080 and, in addition, fixes an SPI timeout bug that made SPI difficult to use. The BNO085 by the motion sensing experts at Hillcrest Laboratories takes the familiar 3- accelerometers, gyroscopes, and magnetometers and packages then alongside an Arm M0 processor running 's -2 firmware that handles the work of reading the sensors, fusing the measurements into data that you can use directly, and packaging that data and delivering it to you. If the name and description of the BNO085 sounds strikingly similar to those of the BNO055 by for Sensortec, there is a good reason why: they're the same thing, but also they're not. Thanks to a agreement between for and , the BNO085 uses the same hardware as the BNO055 but very different firmware running on it. The printing of circuit boards may be slightly different due to different batches, but it does not affect the use.
