This product is the ESP32-CAM [2M] Core Module (PCB only), supplied without the camera lens and without the USB download baseboard. It is a specialized SKU designed for B2B procurement, industrial maintenance, and advanced engineering where the user already has custom optics (such as wide-angle or night-vision lenses) or an existing programming infrastructure.
Product Description
The ESP32-CAM [2M] Core is a high-performance, standalone wireless controller based on the ESP32-S SoC. While it shares the same footprint as the standard AI-Thinker camera module, this “Core-Only” version provides the ultimate flexibility for professional integration. It features the dual-core 240MHz LX6 processor, integrated Wi-Fi/Bluetooth, and 4MB of External PSRAM necessary for image buffering.
By providing the board without a camera, it allows business users to select their own FPC camera modules (such as OV2640, OV7670, or specialized long-flex lenses) without wasting stock lens components. This is the ideal “spare part” or “base component” for high-volume deployments where the camera and programmer are sourced or managed separately.
Key Features
  • Modular Flexibility: Compatible with any standard 24-pin DVP FPC camera (OV2640 recommended).
  • Dual-Core Processing: Xtensa® 32-bit LX6 CPU handles wireless stacks and application logic simultaneously.
  • Built-in PSRAM: 4MB of external Pseudo-Static RAM is included on-board to support high-resolution image processing and web-streaming.
  • Storage Expansion: Integrated MicroSD card slot for local data logging or image storage (up to 4GB).
  • Onboard Flash LED: Features the standard ultra-bright white LED for illumination or signaling.
  • Compact DIP-16 Package: Industry-standard footprint for easy integration into existing PCB backplanes.
Usage Scenarios
  • Business Procurement: Ideal for companies that manufacture custom security devices and source lenses in bulk separately.
  • Maintenance & Repair: Used as a direct replacement core for damaged ESP32-CAM units where the original lens is still functional.
  • Specialized Imaging: For engineers using wide-angle (fisheye) or telephoto FPC cameras that do not come in standard bundles.
  • Industrial IoT: Acts as a powerful Wi-Fi/BT node with SD storage for data logging, even if the camera function is not utilized.
Q: Does this include a camera lens?
No. This is the Core Board only. You must have an OV2640 or compatible 24-pin FPC camera to use the vision features.
Q: How do I program this board without the Download Board?

You will need an external USB-to-Serial (FTDI/CH340) adapter. Connect the adapter’s TX to the board’s RX, RX to TX, and ensure you bridge GPIO 0 to GND during power-up to enter “Flash Mode.”

Q: Can I use any FPC camera with this board?

It is compatible with standard 24-pin DVP interfaces. While most users use the OV2640 (2MP), it can support OV7670, though software configuration will vary.

Q: Why would I buy this instead of the full kit?

This version is cost-optimized for users who already own a programming base (Download Board) or those who are integrating the module into a permanent industrial fixture where a camera is already mounted.

Q: Does it support the 8MB PSRAM features?

This specific SKU is the 4MB PSRAM version. It is sufficient for standard VGA and SVGA video streaming and UXGA still captures.

Q: My board is not powering on. What should I check?
Ensure you are providing 5V to the 5V pin. The ESP32-CAM is notoriously sensitive to voltage. Even if the LED lights up, if the voltage is below 4.75V, the Wi-Fi will fail to initialize.
