Questions
How big is the Chococorne PCB?
It measures 147.4 × 87.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Chococorne use?
69 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 Chococorne KiCad files?
From the davidphilipbarr/testing-boards repository on GitHub, at the commit this page was made from: the board is chocojorne-switch/chococorne.kicad_pcb and its schematic Sweep mid/sweep-mid.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Chococorne design in my own project?
Its repository states no licence, so its author keeps all rights: ask davidphilipbarr before reusing the design.
