Questions
How big is the Battery switch PCB?
It measures 51.1 × 58.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Battery switch use?
40 parts, built around the LTC4417CGN#PBF, SUD50P04-08-VB and BAT54C. 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 Battery switch KiCad files?
From the eclecticc/BeltPack repository on GitHub, at the commit this page was made from: the board is battery_switch/battery_switch.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Battery switch design in my own project?
Its repository states no licence, so its author keeps all rights: ask eclecticc before reusing the design.
