Questions
How big is the Incipit11 PCB?
It measures 43 × 43 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Incipit11 use?
39 parts, built around the EL0631(TA), SPX1117M3-L-3-3/TR, SL54AFL-TP and 0ZCG0160BF2C. 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 Incipit11 KiCad files?
From the DepartmentOfAlchemy/Incipit11 repository on GitHub, at the commit this page was made from: the board is board/Incipit11/Incipit11/Incipit11.kicad_pcb and its schematic board/Incipit11/Incipit11/Incipit11.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Incipit11 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
