Questions
How big is the Keebored PCB?
It measures 47.6 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keebored use?
67 parts, built around the RP2040, W25Q128JVSIQ, TPD4E05U06DQAR and SK6812MINI-E. 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 Keebored KiCad files?
From the MrFriedOk/flickerflame repository on GitHub, at the commit this page was made from: the board is experience/keebored/keebored/rev3/rev3.kicad_pcb and its schematic experience/keebored/keebored/mRev/mRev.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keebored design in my own project?
Its repository states no licence, so its author keeps all rights: ask MrFriedOk before reusing the design.
