The OpenMV H7 Plus Camera is a small, low power, microcontroller board which allows you to easily implement applications using machine vision in the real-world. The Plus variation adds 32 MB of external 32-bit SDRAM and 32 MB of external quad SPI flash. You program the OpenMV Cam in high level Python scripts (courtesy of the MicroPython Operating System) instead of C/C++. This makes it easier to deal with the complex outputs of machine vision algorithms and working with high level data structures. But, you still have total control over your OpenMV Cam and its I/O pins in Python. You can easily trigger taking pictures and video on external events or execute machine vision algorithms to figure out how to control your I/O pins.
The OpenMV Cam H7 Plus comes with a OV5640 image sensor is capable of taking 2592x1944 (5MP) images. Most simple algorithms will run between 25-50 FPS on QVGA (320x240) resolutions and below. Additionally, the OpenMV H7 now features removable camera modules which allow you to use the module with Global Shutter and FLIR Lepton sensors for serious computer vision applications. The OpenMV is perfect for applications involving frame differencing, face detection, eye and marker tracking, QR code detection/decoding, shape detection, and more.
Uses include:
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Got it up and running right away, most of my complaints are minor - like this version is slightly smaller than the H7 - so the 3d printable case designs don't work, the tabs that hold the board are two far apart. I was also annoyed by the HTTPS/SSL client library doesn't support self signed certificates - not the camera's fault (micropython) but it made my application development harder than it needed to be.
All and all, a solid buy if you are looking into playing with machine vision - or even just pre-processing images before uploading them.

Works perfectly. No problem setting it up. I gave it a four because I want more, but can't afford more :)
