Well, first of all: The breakout board built the resistors internally on the board.
Even those installed afterwards had no effect.
There is a long discussion about this with me in the other forum.
I had been testing for weeks!
With 3 different Pi Picos and 3 different BNO005 boards.
I have had the problem confirmed by some users.
But now comes the big end! :
It is not a problem!
There is no point in being faster, as the Fusion output data rates in NDOF mode are 100Hz.
The Bosch data sheet also has an interesting number at
I2C Timings: Clock Frequency: MAX 400 kHz.
An insider told me they actually meant 4 kHz: =)
