Questions
How big is the Fs7-button PCB?
It measures 24 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Fs7-button use?
36 parts, built around the LP5907MFX-3.3. 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 Fs7-button KiCad files?
From the 3nt3/fs7-button repository on GitHub, at the commit this page was made from: the board is pcb/fs7-button.kicad_pcb and its schematic pcb/fs7-button.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fs7-button design in my own project?
Its repository states no licence, so its author keeps all rights: ask 3nt3 before reusing the design.
