A small but very beautiful project.
k3s cluster of four Raspberry Pi Zero 2 W
The parts list is very short, but unfortunately, that doesn’t mean it’s easy to get them now (October 2022):
- Raspberry Pi 4 8Gb
- 4x Raspberry Pi Zero 2 W
- Cluster HAT 2.5
- 802.3at-compliant PoE HAT for Raspberry Pi, it must support up to 4.5A output for Raspberry Pi
- A simple stand
- Feet for the stand from Amazon

And a couple more pictures, enjoy 🙂
P.S.
As you can see I use SD cards, which are very unreliable. The whole project is done in the first place since it looks beautiful.
I use the Raspberry Pi 4 occasionally (Home Assistant is there now), and the cluster was only made as a proof of concept.
