"What is the impact of the SPI flash size on the use of ESP32 firmware? What are the differences between the ESP32-WROOM-32UE-N16 with a 16 MB SPI flash, the ESP32-WROOM-32UE-N8 with an 8 MB SPI flash, and the ESP32-WROOM-32UE-N4 with a 4 MB SPI flash? I noticed that the ESP32 flash is divided into two regions by ESP3D

ESP3D standalone Firmware only need the 4MB Flash because the flash size partition that host the index.html.gz and related files can be set to a minimum of 250KB which let enough space for 2 APP for the updates even for large partitions needed by camera code for example
More flash is actually not really necessary on ESP32 for the moment

Thank you very much.
