You can't buy a Raspberry Pi right now
...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 Pi 400. The Pico and Pico W are both readily available, at least in most markets where I've looked (local shortages always exist, but typically not for months or years like with full-size Pis).
