Works well but runs hot
Functionality is great for streaming video, but the board gets quite warm during extended use. I recommend adding a small heatsink if you plan to run it 24/7.

Best budget camera module
I have tried several ESP cameras, and this version with the OV3660 is the best balance of resolution and cost. The included FTDI adapter made flashing firmware easy.

Good hardware, needs patience to program
The camera quality is excellent for the size. However, uploading code requires holding the boot button, which can be tricky for beginners. Once configured, it works flawlessly.

Ideal for university projects
Used this for my final year project on home security. The Bluetooth and Wi-Fi combo allowed for flexible control options. Documentation online is abundant and helpful.

Compact and powerful
Small form factor fits perfectly into my robot chassis. Image processing speed is decent, though heavy loads can cause slight lag. Overall, a solid development board.

Perfect for IoT Video Projects
This board exceeded my expectations. The OV3660 sensor provides crisp images, and setting up the Wi-Fi stream was straightforward using the Arduino IDE. Great value for the price.
Q: Does this board support 5GHz Wi-Fi networks?
A: No, the ESP32-CAM module only supports 2.4GHz Wi-Fi networks (802.11 b/g/n). It is not compatible with 5GHz bands.
Q: Is the microSD card included in the package?
A: No, the microSD card is not included. The package contains the ESP32-CAM board and the FTDI programming adapter. You will need to purchase a MicroSD card separately.
Q: Can I power this directly from a 3.3V pin?
A: It is recommended to power the board via the 5V pin or Micro USB port. While the chip operates at 3.3V, the camera module and Wi-Fi transmission require stable 5V input to function correctly without brownouts.
Q: What is the maximum resolution for photos?
A: With the OV3660 sensor, the board can capture photos up to 2048x1536 pixels (3MP). You can adjust the resolution in the code to lower settings for faster transmission.
Q: Can this run TensorFlow Lite for image recognition?
A: Yes, the ESP32-CAM supports TensorFlow Lite for Microcontrollers. However, due to memory constraints, models must be optimized and quantized to fit within the available RAM and Flash.
