5. ESP32-S3 supports higher-capacity high-speed Octal SPL flash and off-chip RAM, enabling user configuration of data and instruction caches.

Storage specifications for ESP32-S3 modules:

ESP32-S3-N8R2:

On-chip SRAM: 512K

On-chip ROM: 384K

External PSRAM: 2M

External Flash: 8M

ESP32-S3-N16R8:

On-chip SRAM: 512K

On-chip ROM: 384K

External PSRAM: 8M

Regarding ESP32-S3 Downloading:

ESP32-S3 firmware download/programming can be performed via the ESP32's direct USB interface or through the onboard hardware USB-to-serial converter. Both Type-C USB ports on the board support programming.

In Windows environments, the official flash_download_tool_xxx software may be employed for downloading. Note that these two USB ports utilise distinct methods: one is the USB mode, while the other is the UART mode.
