Two new Raspberry Pi boards have quietly turned up in Raspberry Pi’s Linux kernel tree, and neither of them is quite what I’d have guessed. Device tree files for a Raspberry Pi Zero 3 W and a Raspberry Pi 4 Model A have landed (Phoronix spotted it first), and whilst there’s no official announcement just yet, device tree files tend to give away a surprising amount if you can decipher them and I gave it my best shot.

The Raspberry Pi Zero 2 W launched almost exactly five years ago (tomorrow, in fact), so a successor has been a loooooong time coming. If you want a refresher on where things stood back then, my Raspberry Pi Zero 2 W vs Zero W benchmarks piece covers the jump from the original pretty well.
