Perfect for home security prototypes
I built a motion-detecting camera node for my smart home. The resolution allows me to read license plates in my driveway test setup. The PSRAM helps significantly with buffering high-quality frames.

Great hardware, needs good power supply
The board works perfectly once connected to a stable 2A power source. Initially had reboot loops with a weak USB port, but that's expected with high-res video. The auto-focus speed is impressive for this price point.

Compact and powerful
Small form factor fits easily into my custom drone frame. The auto-focus adjusts quickly when altitude changes. Video latency is low enough for FPV monitoring applications.

Works well but runs hot
Functionality is great and the image quality exceeds expectations. However, the board gets quite warm during continuous 1080p streaming. I added a small heatsink which solved the thermal throttling issue.

Excellent upgrade from the standard OV2640
The auto-focus feature on the OV5640 sensor is a game changer for my robotics project. Image clarity at 1080p is sharp, and the ESP32 handles the stream well over Wi-Fi. Setup with Arduino IDE was straightforward using existing libraries.

Good learning tool for computer vision
Using this for a university project on edge AI. The camera quality is sufficient for basic object detection models. Documentation could be slightly better for the specific auto-focus commands, but community forums helped.
Q: How do I enable the auto-focus feature in code?
A: Auto-focus is typically enabled by calling the specific sensor function in your code, such as `sensor.set_focus_mode(FOCUS_MODE_AUTO)`. Please refer to the example sketches included in the camera library repository.
Q: Can I use this camera with MicroPython?
A: Yes, this board is compatible with MicroPython. You will need to flash a firmware build that includes the ov5640 driver, which is available in recent stable releases.
Q: Is an external antenna included for better Wi-Fi range?
A: This specific model uses the onboard PCB antenna. It does not have an IPEX connector for an external antenna, but the range is generally sufficient for indoor development and testing.
Q: What is the maximum size of the SD card supported?
A: While officially tested up to 4GB, most users successfully utilize FAT32 formatted cards up to 32GB. For larger capacities, exFAT formatting may require additional library support.
Q: Does this board 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). It does not support 5GHz bands.
