- Plug-and-Play Programming: Includes the CH340 Download Base for direct Micro-USB connection—no external adapters or manual “Boot” button sequences required.
- Integrated 2MP Vision: Comes with the OV2640 camera module, supporting high-sensitivity imaging and JPEG, BMP, and Grayscale outputs.
- Memory Optimized: Features 4MB External PSRAM to ensure stable frame buffering for high-resolution video streams.
- Local Data Logging: Onboard MicroSD card slot supports up to 4GB for offline image storage and recording.
- Dual-Core Power: Powered by the 240MHz LX6 CPU for simultaneous image processing and wireless networking.
- B2B Ready: The modular design allows the camera module to be separated from the programmer for integration into final product enclosures.

Standard ESP32-CAM modules do not have a USB port. Without the Download Board, you would need to use an external FTDI adapter and manual wires. The MB board provides a simple Micro-USB port for programming and provides much more stable power to the camera.
Yes, most operating systems require the CH340 driver to recognize the board as a COM port. You can download the latest 2025 drivers from the WCH official website
This is usually due to an inadequate USB cable or port. High-resolution video streaming requires significant current. Use a high-quality Micro-USB cable and connect it to a USB 3.0 port or a 5V/2A wall adapter
Absolutely. Once the code is uploaded, you can unplug the camera module from the baseboard and power it via the 5V and GND pins for a more compact final installation
Select the board “AI Thinker ESP32-CAM”. No additional hardware button presses are usually needed when using the Download Board; just hit “Upload.”
While the connector is compatible, the 4MB PSRAM and processor on the ESP32-S are optimized for the OV2640. A 5MP sensor will significantly reduce the frame rate.
