This is the correct pins used in this boards. GPIO18 and 19 are LEDs and USB JTAG/CDC.

My suggestion based on the boards layout would be:

static const uint8_t SDA = 1;
static const uint8_t SCL = 2;

Fixed with standard ESP32-C3 definition.

the above four pins are not recommended for use or do not exist on the ESP32-C3. These should be remapped to valid pins.

GPIO 0 - 5 are the only ADC pins, GPIO 13 does not exist.
