Integrated SPI Flash and PSRAM size of ESP32-WROER-E module

from product listing for the ESP-WROVER-KIT v4.1.

You can always ask esptool.py to give you the flash size, and you can detect the size of the PSRAM via SPI tool, there are built-in functions for it.

#include <Arduino.h>

void setup() {
  log_d("Total heap: %d", ESP.getHeapSize());
  log_d("Free heap: %d", ESP.getFreeHeap());
  log_d("Total PSRAM: %d", ESP.getPsramSize());
  log_d("Free PSRAM: %d", ESP.getFreePsram());
}

void loop() {}
