The OV2640 is a 2-megapixel camera module that is commonly used in various embedded systems, such as Arduino and ESP32 projects. It is a popular choice for projects involving image capture or video streaming due to its compact size and relatively high-quality output for its resolution.

Here are the key features of the OV2640 camera module:

1. Resolution: 2 Megapixels (1600x1200 pixels)

2. Image Sensor: CMOS (Complementary Metal-Oxide-Semiconductor) sensor

3. Output Formats: Supports YUV422, YUV420, RGB565, and JPEG image formats

4. Low Power Consumption: Designed to be power-efficient, which is important for embedded systems.

5. Lens: Has a fixed-focus lens, with a focal length typically suited for general use.

6. Connectivity: Can be interfaced with microcontrollers like the ESP32 or Raspberry Pi, often via an I2C or SPI interface.

7. Operating Voltage: Typically operates at 3.3V, but may also work at 5V with a level-shifter or suitable protection.

Common Applications:

• IoT Projects: For camera surveillance, video streaming, or image capture in smart devices.

• Robotics: To provide vision capabilities in robots for navigation or object detection.

• Embedded Systems: Integrated into systems that require camera input, such as drones, smart security cameras, and facial recognition projects.
