Hello, I'm trying to connect my own sensor with the I2C bus to the STEVAL-IDP005V2 board. In the datasheet, they say that the I2C2 bus is connected to the auxiliary connector, but on the schematics, nothing is connected. Can you help me please ?

[LMarg.1]

So, is there any solution existing to connect my own sensor with I2C bus to this board ?

My "sensor" is a 15bits adc converter. I would like to send the values of the adc on the io-link bus.

Do you know if it's possible ?

Thanks !!
