Built a nice little PiKVM and deployed it in my NAS. The NAS is heavy and placed in a dark half-height place under the stairs so it’s awkward when things go wrong and you need hardware access.
For those that don’t know what PiKVM is: https://pikvm.org/
They also make this one which uses a CM4 but you can control 4 machines! I have been eying it now that I can get CM4s again, thanks for the post!
