Hi @abo_ali99.
This indicates it has suffered permanent physical damage. You will need to replace it.
But surely never anything close to what could be described as "extremely hot".
This wiring is potentially problematic. When you have the jumper on the FT232R module between the "5V" and middle pins, it uses 5 V logic levels on the RX and TX pins. The ESP32-CAM uses 3.3 V logic levels and so subjecting its RX pin to 5 V is exceeding its maximum rating.
I'm not certain that this was the cause of the physical damage to the ESP32-CAM though, as even though subjecting it to 5 V is a bad idea, many people have done this without encountering any immediately noticeable problem with their ESP32 board.
The obvious alternative would be to instead put the jumper in the "3.3V" position and connect the VCC pin to the "3V3" pin on the ESP32-CAM instead of the "5V" pin. However, this is also problematic because then the VCC pin can't source as much current (it is only rated for 50 mA) and the ESP32-CAM has fairly demanding power requirements. So the ESP32-CAM might not work reliably when powered via the FT232R module in that configuration.
The best solution would be to leave the FT232R module in the "5V" configuration, but use a logic level shifter to convert its 5 V levels to the 3.3 V that is safe for use with the ESP32.
My advice is that when you purchase your replacement ESP32-CAM, buy the one that comes with a "motherboard". This will make the ESP32-CAM much easier to use and you can save your FT232R module for other uses (it is a very useful tool, just not well suited for this specific use case).
