I2C Pins

The schematic excerpt provided below illustrates the wiring configuration for the SDA and SCL lines. Specifically, the SDA line is connected to GPIO 8, while the SCL line is connected to GPIO 9 on the ESP32-S3 module.

The image of the PCB board below depicts the physical locations of the SDA and SCL terminals.
