After much testing and reading many articles here, I’ve managed to configure my ESP32-S3-Wroom-1 N16R8 camera with the PSRAM working and using the ESP-IDF framework.

I bought the board on AliExpress:

https://es.aliexpress.com/item/1005007308040075.html?spm=a2g0o.order_list.order_list_main.5.21ef194dxPKxh9&gatewayAdapt=glo2esp
And the code to configure it is as follows:

esphome:
  name: camara-prueba
  friendly_name: Cámara Prueba
esp32:
  board: esp32-s3-devkitc1-n16r8
  framework:
    type: esp-idf
psram:
  mode: octal
  speed: 80MHz

I hope this can be of help to someone.

Wasn’t there an option for PSRAM size for the compiler in recent changes for certain ESP32 chips?

I’m already specifying it by selecting esp32s3 n16r8 as the board; if I’m wrong and someone knows, please tell me.
