Blueprint
3.3-volt ====> VCC
GPIO 3 (U0R) ===> TX GPIO 1 (U0T) ===> RX GND => GND
- also set the FTDI to 3.3V plus jumping pin GPIO 0 to Ground in the ESP32-CAM. Remove it after programming.
So it goes like this:
To program:
FTDO to 3.3V ESP32 CAM wire from GPIO0 to Ground
To test:
FTDO to 5V Remove ESP32 Cam Wire from GPIO0
