• 1 x OV2640 2MP 120° Wide Angle Camera Module (with integrated 75mm 24-pin FPC)

FREQUENTLY ASKED QUESTIONS (FAQ)

1. What resolution does this camera support? It supports up to 2 Megapixels, providing a maximum UXGA resolution of 1600 x 1200 pixels.

2. Is this compatible with the ESP32-CAM? Yes, it uses the standard 24-pin FPC connector designed perfectly for the ESP32-CAM development board.

3. What does "120 Degree" mean? It refers to the Field of View (FOV). A 120° lens is a "wide-angle" lens, capturing a much broader area than the standard 66° lens.

4. How long is the flexible cable? The FPC cable is 75mm long, as indicated by the "OV2640-75MM" text printed directly on it.

5. How many pins are on the connector? The connector features a standard 24-pin interface.

6. Does it come with a lens cover? Yes, it includes a black plastic cap to protect the glass lens during shipping and installation.

7. Can I adjust the focus? Typically, the lens barrel is threaded; the focus can sometimes be manually adjusted by breaking the small glue seal and rotating the lens.

8. Does this camera have night vision (IR)? No, this is a standard daylight RGB sensor. It does not have the IR-cut filter removed, nor does it have IR LEDs.

9. Can it record video? Yes, it can output video streams. Frame rates vary depending on the host controller, but 15fps at UXGA or higher at VGA is common.

10. Does it have a built-in microphone? No, this module only captures image data. Audio would require a separate microphone module on your microcontroller.

11. What is the operating voltage? It operates on standard 3.3V logic, supplied by the host development board.

12. Are the ribbon cables fragile? Yes, FPC cables are delicate. Avoid sharp creases or repeated bending to prevent breaking the internal traces.

13. Can I use this with a Raspberry Pi? Not directly. Raspberry Pi uses a specific CSI interface. This module requires an SCCB/DVP interface typically found on MCUs like the ESP32.

14. What formats can it output? It supports onboard JPEG compression, which is why it works so well with low-RAM microcontrollers, as well as raw YUV and RGB formats.

15. What is the pitch of the 24-pin connector? It uses a standard 0.5mm pitch.

16. Why use a 75mm cable instead of the standard short one? The 75mm length allows you to mount the camera lens in a different location or angle than the main circuit board, offering much better design flexibility.

17. Does the 120° lens cause a "fisheye" effect? Yes, wide-angle lenses naturally produce some barrel distortion (fisheye effect) at the edges of the image.

18. Which way do the contacts face when plugging it in? Usually, the exposed metal contacts at the end of the cable face down towards the PCB, but always check your specific board's connector.

19. Can I extend the cable further? While FPC extenders exist, extending the cable too far can introduce electrical noise and degrade the image quality. 75mm is a very safe, stable length.

20. Is this suitable for beginner IoT projects? Absolutely; when paired with an ESP32-CAM, it is one of the best setups for learning about web servers and remote image streaming.
