FAQs
1. What is the main difference between this board and a standard ESP32-CAM?
The main difference is the camera module. Standard ESP32-CAM boards usually come with a 2MP OV2640 camera, while this board comes with an OV5640 5MP camera module for higher image resolution.2. Does this ESP32-CAM board have a USB port?
No. This board does not have a built-in USB port. A separate USB-to-TTL serial adapter is required for programming.3. Which board should I select in Arduino IDE?
Select AI Thinker ESP32-CAM in Arduino IDE. Also enable PSRAM before uploading camera examples.4. How do I enter programming mode?
Connect GPIO 0 to GND before powering or resetting the board. After uploading the code, remove the GPIO 0 to GND connection and reset the board.5. What power supply should I use?
Use a stable 5V power supply. For reliable operation, especially during WiFi streaming or flash LED use, a supply capable of good current output is recommended.6. Why does the camera fail to initialize?
Common reasons include weak power supply, PSRAM not enabled, wrong board selection, incorrect camera pin configuration, loose FPC ribbon cable or wrong camera model selected in code.7. Does this board support microSD card storage?
Yes. It has a built-in TF / microSD card slot for storing images locally.8. Can I use WiFi and microSD card together?
Yes, but performance can reduce because the ESP32 is handling camera capture, WiFi transmission and storage operations at the same time.9. What is the onboard white LED used for?
The onboard white LED can be used as a flash or illumination LED. It is connected to GPIO 4.10. Why does the LED flicker when using the SD card?
On ESP32-CAM boards, GPIO 4 is also associated with microSD operation. Because of this shared function, the flash LED may flicker during SD card access.11. Can I connect an external antenna?
Yes, the board has an IPEX / U.FL antenna connector. However, antenna selection may require changing the tiny onboard resistor position depending on the board configuration.12. Can I power it directly from a 3.7V Li-ion or LiPo battery?
Direct connection is not recommended. Use a proper 5V boost converter or regulated power supply to power the board safely.13. Is the OV5640 camera removable?
Yes. The camera is connected using an FPC ribbon cable. Handle the connector carefully while removing or replacing the camera.14. Are all ESP32 GPIO pins available?
No. Many GPIO pins are used internally by the camera and microSD card interface. Only limited GPIO pins are available for external use.15. Can this board be used for AI or face recognition?
It can be used for basic ESP32 camera experiments and compatible ESP32 camera frameworks. Recommended to use ESP32 AI Vision camera for face recognition applications. Click here to buy.
