ESP32-CAM Pinouts:

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
