Questions
How big is the Siltear PCB?
It measures 168 × 90 mm and has 4 copper layers, 4.69 mm thick.
What parts does the Siltear use?
288 parts, built around the CC1101RGP, USBLC6-4, BC848 and FDS4435. 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 Siltear KiCad files?
From the Kreyl/Siltear repository on GitHub, at the commit this page was made from: the board is Siltear_hw/Siltear.kicad_pcb and its schematic Siltear_hw/PChMosfet.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Siltear design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kreyl before reusing the design.
