Perfect for AI Vision Projects
The OV3660 camera quality is surprisingly good for the price. Setting it up with the Arduino IDE was straightforward using the existing libraries. The 8MB PSRAM makes a huge difference when handling image buffers.

Solid performance, runs a bit warm
Using this for a small surveillance robot. The processing speed is great, but it does get warm during continuous video transmission. Added a small heatsink which solved the issue.

Great board, minor documentation gaps
Hardware is solid and Wi-Fi connection is stable. I had to dig into GitHub issues to find the correct pin mapping for the SD card slot, but once configured, it works flawlessly.

Best ESP32 CAM variant yet
The dual-core processor handles multitasking well. I am running face detection and Wi-Fi streaming simultaneously without lag. The build quality feels premium.

Excellent value for money
Compared to other ESP32-CAM variants, the S3 chip offers much better performance. The USB-C port is a welcome addition, eliminating the need for FTDI programmers.

Easy to start learning
As a beginner, I found the examples in the Arduino library manager very helpful. Got my first video stream running in under an hour. Highly recommended for students.
Q: What voltage logic level do the GPIO pins operate at?
A: The GPIO pins on the ESP32-S3 operate at 3.3V logic levels. Do not connect 5V sensors or modules directly to the GPIO pins without a level shifter, as this may damage the board.
Q: Can I power this board directly with a 3.7V LiPo battery?
A: Yes, you can connect a 3.7V LiPo battery to the BAT pins if the board has a charging circuit, or to the VIN pin (which accepts 3.3V-7V). Please check the specific schematic for your revision to confirm the presence of a charging IC.
Q: Does this come with a microSD card slot?
A: Yes, this development board includes a microSD card slot for local storage of images and videos. It supports cards up to 32GB reliably, though larger cards may work depending on formatting.
Q: Is the camera module replaceable if it gets damaged?
A: The OV3660 camera is connected via a flexible flat cable (FFC) connector. Yes, it is replaceable provided you can source a compatible OV3660 module with the same pinout and connector type.
Q: Does this board support 5GHz Wi-Fi networks?
A: No, the ESP32-S3 on this board only supports 2.4 GHz Wi-Fi networks. It does not have 5GHz capability.
