ESP32-CAM WiFi + Bluetooth Camera Module Development Board ESP32 With Camera

The ESP32-CAM WiFi Bluetooth Camera Module combines an ESP32 wireless controller with a compact camera interface and microSD card slot. Its small form factor makes it suitable for embedded camera projects where wireless connectivity and image processing are required.

The module supports WiFi 802.11 b/g/n, Bluetooth 4.2 LE, multiple peripheral interfaces, and several wireless operating modes. It also provides a built-in flash LED for camera illumination and a microSD card slot for external storage.

The ESP32-CAM can be used with the Arduino IDE for custom firmware development. The board can run the CameraWebServer example, providing a browser-based interface for live video streaming and camera configuration.

How It Works

The ESP32-CAM uses the ESP32 platform to control the connected camera and provide wireless communication. The camera captures images that can be processed or transmitted through the ESP32's WiFi connection.

For a basic test, connect the camera ribbon cable carefully to the FPC connector and insert a compatible microSD card if required. Power the board using a suitable programmer and USB power source. With the supplied firmware, the board can create a WiFi network such as ESP32-CAM or HW297C.

Connect a smartphone or computer to the ESP32-CAM WiFi network and open 192.168.4.1 in a web browser. The camera interface can then be used to start the video stream.

For custom programming, install the ESP32 board package in Arduino IDE and select AI-Thinker ESP32-CAM. The CameraWebServer example can be configured with the appropriate camera model and WiFi credentials before uploading the firmware.

Note: Partition Your 16GB or 32 GB card to 4GB and allocate rest of the storage to Unallocated space to make your large memory card work as a 4GB memory card to work on the ESP32-CAM

Important Notes

• The camera ribbon cable must be connected correctly before using the camera.
• The camera connector and ribbon cable are delicate; avoid forceful insertion.
• Use a good-quality USB cable and a stable power source, especially when the camera and flash LED are active.
• The supplied product may already have default firmware installed; do not upload new firmware unless custom programming is required.
• A compatible microSD card may be required for applications using external storage.
• The actual camera module supplied may vary depending on the production version.
• Product images are for illustrative purposes and may differ from the actual product.
• Camera performance, supported resolutions, and features depend on the installed camera module and firmware.
• Ensure the correct board model is selected when programming through Arduino IDE.
• Do not exceed the recommended 5V power input.
• Power consumption can increase significantly when the camera flash LED is enabled.
