MT9T112 – 3.0 MP Camera Module:
The MT9T112 – 3.0 MP Camera Module is based on the MT9T112 color sensor from Micron/Aptiva. The sensor has a 1/4.0″ optical format, which combined with the pixel size of 1.75 µm x 1.75 µm, provides the 3.1 MP 2048 x 1536 QXGA image. This is a rolling shutter sensor, which captures an entire column (or row) simultaneously, and compiles the image by scanning across (or down).
This adapter board does not offer a standard (M12 or CS) lens mount, but uses the “stock lens” supplied with the sensor. However, additional camera modules with similar sensors are available from ArduCAM. See OV3640 – 3.0 MP Camera Module for other 3.0 MP camera options. These are available bundled with an LS-27227 M12 lens, or with a variety of M12 mount and CS mount options, and any compatible lens, sold separately.
The key benefit of the standard lens mounts available with this module is the simplicity in swapping the lens – fisheye, wide-angle, telephoto, zoom, IR or NoIR filter – all of which are available from DLSCorp. Click on the Camera Lenses product category for the complete selection of ArduCAM lenses. Be sure to note the compatible lens mount height (7 mm, 10 mm, or 14.5 mm) for each lens selected if you chose an M12 metal mount option. Note, each lens purchased separately comes with its appropriate height lens mount (plastic for M12, metal for CS), so you may choose to purchase the camera with only a generic plastic lens mount (to protect the sensor). Click on the Camera Lens Mounts product category for information about lens mounts, including compatibility with the various 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″ pitch connector. Or, you will need to purchase one of the available ArduCAM camera shields. The ArduCAM USB Camera Shield provides you a USB connection to a Windows, Linux, or Raspberry Pi computer for these camera modules. You may use the ArduCAM F Shield Rev C+ or the ArduCAM LF Shield Rev C+ to connect to Arduino system boards. 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.
