Compact and powerful
The form factor is tiny yet packed with features. Bluetooth pairing worked instantly with my phone. Using it as a wireless doorbell camera now.

Good documentation available online
As a beginner, I was worried about setup, but there are plenty of tutorials online. The only downside is the lack of a built-in USB-to-serial converter, so you need an FTDI programmer.

Perfect for IoT Video Projects
This board works flawlessly out of the box. I was able to stream video to my local server within an hour of unboxing. The PSRAM makes a huge difference for image buffering.

Ideal for student projects
Bought five of these for a university robotics class. Students found the Arduino library support very easy to use. Face detection examples run smoothly.

Reliable for prototyping
Used this for rapid prototyping of a security system. The dual-core processor handles network tasks and camera capture simultaneously without lag. Highly recommended.

Great value but needs careful power supply
Excellent camera quality for the price. Just make sure you use a stable 5V power source; otherwise, it might reboot during Wi-Fi transmission. Once powered correctly, it is very stable.
Q: Does it support 5GHz Wi-Fi networks?
A: No, the ESP32 chip on this board only supports 2.4GHz Wi-Fi networks (802.11 b/g/n).
Q: Can I power this directly from a 3.3V pin?
A: No, please do not power it via the 3.3V pin. It requires a stable 5V input because the Wi-Fi module draws significant current that can cause voltage drops on 3.3V lines.
Q: What programmer do I need to upload code?
A: Since there is no onboard USB interface, you will need a separate USB-to-TTL serial converter (like FTDI or CP2102) to flash firmware onto the board.
Q: Is the camera lens replaceable?
A: The OV2640 sensor is soldered directly to the board, but the plastic lens cap can be removed if you wish to attach external optics, though this requires careful handling.
Q: Does this board come with an SD card slot?
A: Yes, the ESP32-CAM module includes a microSD card slot for local storage of images and video recordings.
