Questions
How big is the BitSwitch PCB?
It measures 31 × 16 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BitSwitch use?
4 parts, built around the 74HC165D. 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 BitSwitch KiCad files?
From the emab123/BitSwitch repository on GitHub, at the commit this page was made from: the board is BitSwitch.kicad_pcb and its schematic BitSwitch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BitSwitch design in my own project?
Its repository states no licence, so its author keeps all rights: ask emab123 before reusing the design.
