Questions
How big is the Button box PCB?
It measures 96.4 × 66.4 mm and has 4 copper layers, 1.59 mm thick.
What parts does the Button box use?
30 parts, built around the SP0502BAHTG, NTR4503NT1G, 1812L075PR and HC-TYPE-C-16P-01A-L. 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 Button box KiCad files?
From the robin7331/eufy-remote-control repository on GitHub, at the commit this page was made from: the board is hardware/button-box/pcbs/button-box/button-box/button-box.kicad_pcb and its schematic hardware/button-box/pcbs/button-box/button-box/button-box.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Button box design in my own project?
Its repository states no licence, so its author keeps all rights: ask robin7331 before reusing the design.
