Questions
What parts does the Locket use?
76 parts, built around the CC1101RGP, MMA8452QT, BAT54WS and IRLML9303. 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 Locket KiCad files?
From the Kreyl/Locket repository on GitHub, at the commit this page was made from: the board is Hardware/Locket.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Locket design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kreyl before reusing the design.
