- **flash_size** (*Optional*, string): The amount of flash memory available on the ESP32 board/module. One of ``4MB``,
``8MB``, ``16MB`` or ``32MB``. Defaults to ``4MB``. **Warning: specifying a size larger than that available on your
board will cause the ESP32 to fail to boot.**

``esp32s2``, ``esp32s3``, ``esp32c3`` and ``esp32h2``. Defaults to the variant that is detected from the board, if
