What should I do when the RAM capacity of ESP32 is low?

The current project needs to temporarily store a lot of data, and the several hundred K RAM that comes with it is not enough, I read the datasheet, ESP32 supports external FLASH and SRAM, so please ask if these are additional purchases? Or is it integrated on the chip and can be called directly?

Hi,
All the ESP32's have external flash memory (some chips the flash memory are inside the SoC, like the ESP32-U4 and ESP32-PICO). You can use the flash memory to store your data. The PSRAM is also supported on the ESP32 and some modules already have it.
