Dear @TEASTAIN2,
thanks for your input, I have tried this but it was not working.
I found a qwiic connector and on that port it works but not on the pin header, any idea?
They should be connected together. (the multmeter confirm)
Maybe noise on board... I will investigate further.

thanks anyway

Hi,
does anyone have goo experience with I2C on this board, I'm struggling to make it work, the pinout is not clear, I have tried using pin 43 and 44 and the I2C scanner doesn't report anything connected, even if the sensor work perfectly on a different vendor board. What library should be used for I2C on this specific board, are the pin correct?
Thanks. E.
