MT9D111 – 2.0 MP Camera Module:
The MT9D111 – 2.0 MP Camera Module features the MT9D111 color sensor from Micron/Aptina. The sensor has a 1/3.2″ optical format, which combined with the pixel size of 2.8 µm x 2.8 µm, provides the 2.0 MP (1600 x 1200) 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 bundled camera modules include the LS-2718CS lens (NoIR) w/ metal CS mount (B0009) or the LS-6020 lens (IR or NoIR) w/ metal M12 mount (B0010). They are also available without a lens – just a generic plastic lens mount to protect the sensor during shipping; the lens mount supplied with your lens purchased separately replaces the generic mount. Available separately are higher quality metal M12 or CS lens mount, or a motorized IR cutoff filter mount. For the motorized IR cutoff filter mount, the user must supply the 5-18 V power. Also, see the MT9D111 – 2.0 MP Camera Sensor w/ Autofocus Stock Lens on Adapter Board (B0054) for an autofocus option.
The key benefit of the standard (CS and M12) 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, etc.) for each lens selected if you chose an M12 metal mount option. Each lens purchased separately comes with a compatible height lens mount (plastic for M12, metal for CS). 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 may purchase one of the available ArduCAM camera shields.
The ArduCAM USB Camera Shields USB2 Rev D (B0095) or USB3 Rev C (B0111) and Parallel Adapter Board (B0126) provide you a USB connection to a Windows, x86 Linux, Nvidia Jetson, or Raspberry Pi computer for these camera modules. You may also use the ArduCAM F Shield Rev V2 (B0051) or ArduCAM LF Shield Rev V2 (B0052) to connect to Arduino system boards. Open-source software and binaries are provided on the ArduCAM GitHub site (see link below) for these shields.
