-The schematic excerpt provided below illustrates the wiring configuration for the __SDA__ and __SCL__ lines. Specifically, the __SDA__ line is connected to _GPIO 18_, while the __SCL__ line is connected to _GPIO 19_ on the ESP32-C3 Wroom module. The image of the PCB board below depicts the physical locations of the __SDA__ and __SCL__ terminals.
