Review on 📷 Arducam Multi Camera Adapter Module V2.2: Utilize Multiple 5MP or 8MP Cameras on Raspberry Pi 4 B, 3B+, Pi 3, Pi 2, Model A/B/B+ by Julio Diaz

The documentation is fine - there are Python and C++ demo scripts. The readme is most up-to-date for C++, but I was able to determine the Python version fairly easily. The multicam adapter works, but is unfortunately unstable. One day it will work perfectly and be able to switch between cameras or launch cameras at the same time. But the next day you get errors without making any changes. If they can offer stability, that's a great solution.
