Questions
How big is the Large button PCB?
It measures 43.4 × 42 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Large button use?
16 parts, built around the FRC0603J151 TS, CPG135001D01, M2.5 and HL-AM-2835D1W-S1-08-HR3. 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 Large button KiCad files?
From the synthesissolutions/geeksforkids repository on GitHub, at the commit this page was made from: the board is hardware/Drive Systems/Control Panel (New)/Large_Button/large_button.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Large button design in my own project?
Its repository states no licence, so its author keeps all rights: ask synthesissolutions before reusing the design.
