I2C configuration
One I2C interface I2C_DEV(0) is defined and available via the SAO headers. The GPIOs listed in the configuration are only initialized as I2C signals when module `periph_i2c` is used. Otherwise they are not allocated and can be used for other purposes.
#define	I2C0_SPEED I2C_SPEED_FAST
	I2C bus speed of I2C_DEV(0)

#define	I2C0_SCL GPIO6
	SCL signal of I2C_DEV(0)

#define	I2C0_SDA GPIO5
	SDA signal of I2C_DEV(0)

UART configuration
ESP32-C3 provides 2 UART interfaces at maximum: UART_DEV(0) uses fixed standard configuration. UART_DEV(1) is used for IrDA (untested).
#define	UART0_TXD GPIO21
	direct I/O pin for UART_DEV(0) TxD, can't be changed

#define	UART0_RXD GPIO20
	direct I/O pin for UART_DEV(0) RxD, can't be changed

#define	UART1_TXD GPIO7
	IrDA TX - Bad Choice?

#define	UART1_RXD GPIO3
	IrDA RX - Bad Choice?
