Questions
How big is the Power switch PCB?
It measures 31 × 22.6 mm and has 2 copper layers, 0.6 mm thick.
What parts does the Power switch use?
28 parts, built around the BQ24075RGT and RT0402BRD071K87L. 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 Power switch KiCad files?
From the Max585t/Every83 repository on GitHub, at the commit this page was made from: the board is Power_Switch/power_switch.kicad_pcb and its schematic Keyboard_Matrix.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power switch design in my own project?
Its repository states no licence, so its author keeps all rights: ask Max585t before reusing the design.
