Raspberry Pi OS Lite with Hyperion pre installed. Also called HyperBian.
We provide two different versions (arm64/armhf) according to your preferred hardware platform.
Recommendation:
Use the arm64 image to benefit from a true 64 bit system.
In case you run a Raspberry Pi 1, 2 or Zero v1, go for the armhf one.
Find the installation instruction at the Hyperion documentation site.
