Great value but needs external programmer
The board works well once you get it running. Just remember it doesn't have a built-in USB-to-UART converter, so you must use the included FTDI adapter for uploading code. Once configured, the Bluetooth and Wi-Fi connectivity are stable.

Great starter board for ESP32
As someone new to microcontrollers, this was a fun challenge. The community support is huge, so finding sample code for video streaming was easy. Deducting one star because the pinout diagram on the back is a bit faint.

Compact and powerful
Impressed by how small this board is while still packing Wi-Fi, Bluetooth, and a camera. I used it to build a time-lapse camera for my garden, and it has been running reliably on battery power for weeks.

Excellent for learning embedded vision
I bought this for a university project on object detection. The processing power of the ESP32 combined with the camera module handles basic TensorFlow Lite models surprisingly well. Documentation online is abundant which helped a lot.

Perfect for IoT Vision Projects
This board is exactly what I needed for my home security camera project. The OV2640 sensor provides decent image quality for the price, and setting up the Wi-Fi stream was straightforward using the Arduino IDE. Highly recommended for hobbyists.

Good hardware, tricky initial setup
The hardware seems solid, but getting the drivers installed for the FTDI programmer took some troubleshooting on Windows 11. After that hurdle, the board performs as expected. Image quality is acceptable for indoor monitoring.
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 an SD card slot available for local storage?
A: Yes, the board features a microSD card slot on the bottom side, allowing you to save images or video clips locally without needing a constant network connection.
Q: Which software libraries are best for face detection on this board?
A: You can use the ESP32 Face Detection example included in the ESP-IDF framework or look for Arduino libraries like 'esp32-camera' which often include face recognition demos optimized for this hardware.
Q: Can I power this board directly via the Micro USB port?
A: Yes, you can power the board via the Micro USB port using a standard 5V supply. However, when using the FTDI programmer for code uploads, ensure the jumper cap is set to the correct voltage position.
Q: What is the maximum resolution of the camera?
A: The OV2640 sensor supports resolutions up to UXGA (1600x1200 pixels), though higher resolutions may result in lower frame rates depending on your Wi-Fi bandwidth and processing load.
