Hi, I want to know Is the IMU sensor BNO085 can detect the angle it rotates in degree?

Hi Yiyang,

As listed in the product description, one of the many data streams coming out of this IMU is absolute orientation:

All the best with your project and let us know if you have any more questions!

I have had problems consistently reading this unit on a Raspberry Pi 4b over I2C, and I’ve tried the imbalanced resistor trick as well as SW I2C interfaces to no avail. Furthermore, I can’t get it functioning in either UART or SPI modes. Has anyone else met similar difficulties? I had similar problems with BNO055.


Hi Joni,

The first step is to post the code you’re running, the output of sudo i2cdetect -y and a picture of what your setup looks like.

Once you’ve sent that through we can have a better look into what’s causing your problems.
