LoRa 32 V3: OLED_SDA / OLED_SCL Pin Locations

[CCS86]

Hello, I am trying to connect a SCD41 sensor to my Wifi LoRa 32 V3 board.

My understanding is that the sensor's SCL / SDA pins should connect to the board's OLED_SDA / OLED_SCL, but I am not understanding the pinout diagram:

Are these pins under the display or something? I don't see physical pins on the J2 / J3 headers to make this connection.

Any help is appreciated!

I think I figured out that GPIO 41 and 42 can be used for this.

Yes.
Read the variants pins file to know what is used by default. I2C is also made up so you can use almost any GPIO pair as long as they are defined. I would stick with what is already defined.
