...or at least, not without a lot of patience or a fat wallet. But why? And are there any signs Raspberry Pis will become available to the general public again soon? To be clear, I'm speaking of the mainstream SBC Raspberry Pis, like the Pi 4 model B, the Compute Module 4, the Pi Zero 2 W, and even in many cases the…
