I made this with beefy graphics projects in mind, to be able to whitstand larger graphics :) I also really wanted to have a custom devboard that suits my needs and can work for all my project prototypes!
This is it built and soldered up:

Questions
How big is the Catboard PCB?
It measures 21.5 × 51.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Catboard use?
33 parts, built around the RP2040 and W25Q128JVPIQ. 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 Catboard KiCad files?
From the katetriestocode/catboard repository on GitHub, at the commit this page was made from: the board is pcb/catboard.kicad_pcb and its schematic pcb/catboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Catboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask katetriestocode before reusing the design.
