The latest revision of the Arducam Multi Camera Adapter is V2.2. The V2.2 undergoes firmware updates, but the specs, documentations, and tutorials on the V2.1 will still apply to the V2.2.
Considering that the high-speed CSI camera MIPI signal integrity is sensitive to a long cable connection, this adapter board does not support stacking and can only connect 4 cameras at maximum. Because It covers most of the use cases like 360-degree view photography and surveillance, adding more cameras will degrading the camera performance.
The previous model work with Raspbian 9.8 and backward, and does NOT work with Raspbian 9.9 and onward, so this model is out to tackle this issue.
Please note that Raspberry Pi multi-camera adapter board is a nascent product that may have some stability issues and limitations because of the cable’s signal integrity and RPi's closed source video core libraries, so use it at your own risk.
