Questions
How big is the Dropin PCB?
It measures 233.9 × 89.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dropin use?
106 parts. 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 Dropin KiCad files?
From the Spaceboards/SpaceboardsHardware repository on GitHub, at the commit this page was made from: the board is Keyboards/Pancake/V1/kicad/dropin.kicad_pcb and its schematic Keyboards/Waffle/kicad/Pancake_v8.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dropin design in my own project?
Its repository publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
