Questions
How big is the PCB V3.1 PCB?
It measures 80 × 160 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PCB V3.1 use?
299 parts, built around the PE4251MLI-Z, CC1101RGPR, DG2001EDV-T1-GE3 and B0310J50100AHF. 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 PCB V3.1 KiCad files?
From the Jonathan-0101/skeletonKey repository on GitHub, at the commit this page was made from: the board is Hardware/PCB V3/PCB V3.1/PCB V3.1.kicad_pcb and its schematic Hardware/PCB V1/PCB V1.0/PCB V1.0/PCB V1.0(PN5180).kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCB V3.1 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
