Questions
How big is the Minigeki PCB?
It measures 151.8 × 78.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Minigeki use?
68 parts, built around the RP2040, W25Q128JVSIQ, SK6812MINI-E and PTA4543-2015DPB103. 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 Minigeki KiCad files?
From the defvs/minigeki repository on GitHub, at the commit this page was made from: the board is hw/minigeki.kicad_pcb and its schematic hw/minigeki.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Minigeki design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
