How big is the Small Button PCB?
It measures 20.8 × 20.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Small Button use?
7 parts, built around the FRC0603J151 TS, CPG135001D01, SM03B-SRSS-TB(LF)(SN) 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 Small 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)/Small_Button/Small_Button.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Small Button design in my own project?
Its repository states no licence, so its author keeps all rights: ask synthesissolutions before reusing the design.
