Hi, I'm trying to attach a BME280 sensor to my Lilygo TTGO LoRa T3-S3 that I just bought, but the pinout on the site is not correct.
As you can see, the pins of the I2C bus (SDA, SCL) are documented as pin 18 and 17, but these pins doesn't exist on the pinout....
where should I connect my I2C sensor?

17 and 18 are used for the oled. You can use other pins
