Questions
What parts does the Projected use?
46 parts, built around the STM32L432KBU6, PCA9306DCUR and BC847CL. 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 Projected KiCad files?
From the jonnor/projects repository on GitHub, at the commit this page was made from: the board is jewelry/projected/projected/projected.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Projected design in my own project?
Its repository states no licence, so its author keeps all rights: ask jonnor before reusing the design.
