The ESP32-CAM doesn’t come with a USB connector, so you need an FTDI programmer to upload code through the U0R and U0T pins (serial pins).
There are three GND pins and two pins for power: either 3.3V or 5V.
GPIO 1 and GPIO 3 are the serial pins. You need these pins to upload code to your board.
Additionally, GPIO 0 also plays an important role, since it determines whether the ESP32 is in flashing mode or not.
When GPIO 0 is connected to GND, the ESP32 is in flashing mode.
The following pins are internally connected to the microSD card reader:
GPIO 14: CLK
GPIO 15: CMD
GPIO 2: Data 0
GPIO 4: Data 1 (also connected to the on-board LED)
GPIO 12: Data 2
GPIO 13: Data 3
