EBB 42 v1.2 i2c Bus #189

Description

Hi,

I can't find any documentation about the i2c bus / pins apart from the pin names PB3 and PB4 on the pinout graphic.

There is no example in https://github.com/bigtreetech/EBB/blob/master/EBB%20CAN%20V1.1%20and%20V1.2%20(STM32G0B1)/sample-bigtreetech-ebb-canbus-v1.1.cfg

How do I set up a standard BME 280 sensor?
I presume PB3 is SCL and PB4 is SDA, but well, it's not dcumented?

How should a klipper config and a query macro look like?
