@teastain2 Mistery solved, it was that specific board with some soldering issues, I got another one and works perfectly

@smile6905 What sensor are you using?
I use the qwiic connector for all I2C and occasionally non-I2C sensors and the side pins as well with no problems. As I said the Wire.begin(SDA, SCL) 43, 44 is very important
Sorry you are having difficulties, keep trying!

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

Wire.begin(SDA, SCL) which is

Wire.begin(43, 44);
