Maximum data refresh rate is about 250Hz??? #4

Datasheet says (page 17):

Gyroscope Sample Rate, Fast: 8 kHz

Accelerometer Sample Rate: 1 kHz

What if we read only what matters?

For example, if we read all the data, it will take a longer time than reading only one axis!

Of course you can read only the data you need. According to datasheet, MPU60X0's maximum SCL clock is 400khz, although ESP32 supports maximum of 2mhz. In my practice when reading all the data the data rate is at most 250hz.

Yes, but to say it in a few words may be enough for the unsuspecting to discard the use of this sensor, which is why I reported the case.
