What are the SDA and SCL pins on this ESP32 model?, specifically ESP32-S3-WROOM-1U-N4

The ESP32 series do not have dedicated I2C pins; you can use any IO-pin that is not otherwise occupied.

The SDA and SCL pins on the ESP32-S3-WROOM-1U-N4 are assignable. Common defaults are:
SDA: GPIO 8
SCL: GPIO 9
You can change these pins in your code based on your setup.
