Questions
How big is the MinCab PCB?
It measures 55 × 14.7 mm and has 4 copper layers, 4.69 mm thick.
What parts does the MinCab use?
41 parts, built around the 74LVC1G07SE-7-MS, CP2102N-A02-GQFN20, RT9742GGJ5 and SP0503BAHTG. 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 MinCab KiCad files?
From the merocle/mincab repository on GitHub, at the commit this page was made from: the board is MinCab_v3.0/Kicad project/MinCab.kicad_pcb and its schematic MinCab_v1.0/Kicad project/MinCab.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MinCab design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
