Hello people  If the staff of DJI can help me . There is an internal serial number that I know through the log sent to healthdrones site . This serial number is on the IMU ? It can be changed , or it changes only if the IMU is changed ?  Thank you!

No, the serial number cannot be changed.
In the About page it will give you the serial number of the flight controller.

I am curious as to why you ask. Are you having problems with the IMU? I am having issues with mine and wonder if anyone else is having a drifting issue in ATTI mode.
