Default Pins

These pins are the default pins, however they can be remapped to any other gpio.
I2C

Default pins are:

    gpio.9 SCL
    gpio.8 SDA

There is an aditional I2C interface which does not seem
 to have default pins (wip).
SPI

The ESP32 S3 has four SPI interfaces which are:
    SPI0 used by ESP32-S3’s cache and Crypto DMA (EDMA) to 
    access in-package or off-package flash/PSRAM
    SPI1 used by the CPU to access in-package or 
    off-package flash/PSRAM
    SPI2 is a general purpose SPI controller with
     its own DMA channel
    SPI3 is a general purpose SPI controller with 
    access to a DMA channel shared between several peripherals

The SPI2 (FSPI) default pins are:

    gpio.12 SCK Defined as SPI0_SCK
    gpio.11 MOSI Defined as SPI0_MOSI
    gpio.13 MISO Defined as SPI0_MISO
    gpio.10 CSO Defined as SPI_CS0

SPI3 does not have default pin mappings because it
 can be mapped to any available gpio pins.
I2S

The ESP32 S3 has two I2S interfaces which can be 
mapped to any available gpio pins.
