Arducam Multi Camera Adapter Module V2.2 for Raspberry Pi 4, 3B+, Pi 3, Pi 2, Model A/B/B+, Work with 5MP or 8MP Cameras

After a relatively straightforward installation, I started noticing serious errors. First, the board did not work and it was not read by the Raspberry Pi. I wasted many hours through blogs full of complaints of users not able to use it, and I now understand why:Otherwise as shown in its advertisement on Amazon and on the Arducam website, this board is not good for videos. In fact, it makes such that cameras take quick pictures and not videos, and kind of stitch them together, to give this feel that a continuous stream is being initiated.The cameras cannot run simultaneously. Again, not fully explained when reading the description on Amazon and on the Arducam website, and is only readable on the paper documentation that comes with the product, once purchased.When the adapter is reported as faulty by the users, the usual response of the manufacturer's technical team is to replace the cable, as faulty. This is incorrect and misstated, as what happens in fact, is that the board absorbs too much power and GPU memory from the board and it causes it to "freeze". I could test this as, whereas the script "sudo ./init_camera.sh" was returning a "camera not found error", when instead I reduced the number of cameras from three to 2, updating the boot file too, then, no matter the ports chosen. The adapter would be indeed recognised, and the images produced.The conclusion is that this board has been badly engineered, incorrectly explained and supported, and creatively advertised and that it is ultimately, a very bad product.
