Setup
KiCAD Library Setup
Run the following command to install the third party KiCAD libraries used in the project
git submodule update --init --recursive
This project uses components from digikey-kicad-library which is configured as a git submodule of this project. Git doesn't clone submodules of a project by default when the project it is cloned so this has to be done manually.

Questions
What parts does the Relelauta use?
150 parts, built around the TLV75533PDBV, IRLZ44N and WS2812B. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Relelauta KiCad files?
From the chiplet/kapine repository on GitHub, at the commit this page was made from: the board is hw/relelauta/v2/relelauta/relelauta.kicad_pcb and its schematic hw/motherboard/main/main.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Relelauta design in my own project?
Its repository states no licence, so its author keeps all rights: ask chiplet before reusing the design.
