what do you think of these sattic curves ?

For the rate, be care with the scale.
That is with the new IMU. May be something wrong on the board again.

nobody to answer ?

Apart from a bit of noise on the Z-gyro, I see nothing wrong. The noise could very well be from condensation on the board - make another try and see what you come up with. But the noise is very low magnitude and I think you should be able to generate a result regardless.

Can you post a plot of voltages 0,1,2

You are heating very fast, maybe you need to use a larger box or less insulation.

many thanks jussiH. see the voltage:
I was surprised by the magnetic curves going up and down. I had not that with my old STM.

No problems, it should work just fine.

The mag curves going up and down is a perfect example of the difference between individual sensors and ADC´s and underline why calibration is so important

[plexus]

OK jussih
I am going to redo the static calibration putting the board in an other box to see if it is better.
