Hi Vlad, The axes are not always the same for Accelerometer and Gyro indeed. (it depends on which Shimmer versions you use and which Gyro board you use) I made some illustrations to show the directions for these 2 combinations a while ago; - Shimmer 1.3 + Flexible Gyro - Shimmer 2R + Rigid Gyro You can find these illustrations attached.

Using shimmer 2R. I have a basic question, are the gyro and accelerometer x and y axes the same? I know that rotating about the accelerometer z axis I get angular velocity on the gyro z axis. Rotating about the accel x axis, however, I get angular velocity on the gyro y axis. Rotating about the accelerometer y axis, I get angular velocity on the gyro x axis. Is this the expected operation?
