OV2640 2MP Camera Module for ESP32-CAM

The OV2640 2MP Camera Module for ESP32-CAM & amp is an image sensor made by OmniVision that outputs 2 megapixels through a parallel data interface connecting to the camera input of an ESP32-CAM board. The OV2640 2MP Camera Module captures still images at up to 1600 x 1200 pixels and video at lower resolutions — the ESP32-CAM’s processor handles frame capture, compression, and wireless transmission.  The 24-pin FPC ribbon connector seats directly into the ESP32-CAM camera slot, which is the standard connector format for this sensor family.

The ov2640 camera module 1/4 inch optical format lens determines the physical sensor size and the achievable field of view for a given focal length. The I/O power supply range of 1.7V to 3.3V matches the ESP32’s 3.3V GPIO and camera interface voltage directly — no voltage level shifting is needed between the sensor and the ESP32-CAM Module. Signal-to-noise ratio of 40 dB is modest by imaging standards — sufficient for motion detection, object recognition, and surveillance streaming, but not suitable for photography requiring fine detail or low-noise imaging in dim conditions.

The OV2640 sensor integrates automatic exposure control, automatic white balance, and automatic gain control on-chip, reducing the firmware complexity needed to capture usable images in varying light. The esp32 cam ov2640 combination is the most documented camera-plus-wireless platform available for embedded imaging in the maker community. This Camera module available on StemVolt, and its working on ESP32 camera module and practical embedded vision projects.
