Not too sure why it's saying 2MB external flash, I'm pretty sure the esp32-cam has a 4MB flash. but I think it's inside the metal casing of the module so I can't check, the psram is outside the module though so I'm sure about its size (ESP-PSRAM64H)

here is a schematic for the esp32 cam, it has the psram pinouts: https://i1.wp.com/randomnerdtutorials.com/wp-content/uploads/2020/03/ESP32-CAM-AI-Thinker-schematic-diagram.png?quality=100&strip=all&ssl=1
