OV2640A – 2.0 MP SCCB Camera Sensor on Adapter Board:
The OV2640A – 2.0 MP SCCB Camera Sensor on Adapter Board is based on the OV2640 color sensor from OmniVision. The sensor has a 1/4.0″ optical format, which combined with the pixel size of 2.2 µm x 2.2 µm, provides the 2.0 MP 1600 x 1200 UXGA image. This is a rolling shutter sensor, which captures an entire column (or row) simultaneously, and compiles the image by scanning across (or down).
The advantage this board has is the easy exchange of sensors – since the sensor plugs into the boards, simply remove and replace the sensor. The disadvantage is the adapter board does not offer a standard (CS or M12) lens mount, but uses the “stock lens” supplied with the sensor. However, additional camera modules with the same sensor are available from ArduCAM. For example, you can purchase the OV2640 – 2.0 MP Mini Module bundled with an M12 lens. Or, you can customize your solution with either an M12 or a CS mount, and any compatible lens, sold separately. Click on the Camera Lens Mounts product category for information about lens mounts, including compatibility with the various lenses. Then, click on the Camera Lenses product category for the complete selection of ArduCAM lenses.
In the Arduino world, a “shield” is a piggy-back circuit board that provides additional functionality to the development board. In this context, a camera shield provides the required interface from the camera module to your computer. You may choose to create your own custom-built hardware interface via the 20-pin 0.1″ / 2.54 mm pitch connector. Or, you will need to purchase one of the available ArduCAM camera shields. The ArduCAM USB Camera Shield provide you a USB connection to a Windows, Linux, or Raspberry Pi computer for these camera modules. Open-source software and binaries are provided on the ArduCAM GitHub site (see link below) for these shields. ArduCAM supplies a wide variety of camera modules that are compatible with their USB Camera Shields, and all are available from DLSCorp.
