Questions
What parts does the 40+ pcb use?
143 parts, built around the USB6B1 and 2450AT43B100E. 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 40+ pcb KiCad files?
From the nzge/input-peripherals repository on GitHub, at the commit this page was made from: the board is forty/40+/40+_pcb/40+_pcb.kicad_pcb and its schematic _kicad-components/ScottoKicad/ScottoModules/STM32F072CBT6/ScottoModules.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 40+ pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask nzge before reusing the design.
