Questions
How big is the Demo PCB?
It measures 41.9 × 25.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Demo use?
18 parts, built around the BC547. 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 Demo KiCad files?
From the 0x007E/kicad repository on GitHub, at the commit this page was made from: the board is pcb/demo.kicad_pcb and its schematic pcb/demo.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Demo design in my own project?
Its repository states no licence, so its author keeps all rights: ask 0x007E before reusing the design.
