Questions
How big is the Winchesterduino PCB?
It measures 99 × 84.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Winchesterduino use?
25 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 Winchesterduino KiCad files?
From the climatex/Winchesterduino repository on GitHub, at the commit this page was made from: the board is Boards/Main/Main.kicad_pcb and its schematic Boards/Main/Main.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Winchesterduino 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).
