Questions
How big is the Flippa PCB?
It measures 99 × 28.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Flippa use?
30 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 Flippa KiCad files?
From the wolf-bage/KiCad_work repository on GitHub, at the commit this page was made from: the board is folder2/flippa.kicad_pcb and its schematic folder2/flippa.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Flippa design in my own project?
Its repository states no licence, so its author keeps all rights: ask wolf-bage before reusing the design.
