Questions
How big is the CSAD10 PCB?
It measures 56.3 × 45.9 mm and has 4 copper layers, 1.61 mm thick.
What parts does the CSAD10 use?
65 parts, built around the LTC6957IMS-3, AP7361C-33E, LMK00101SQ and U.FL-R-SMT(01). 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 CSAD10 KiCad files?
From the myriadrf/lc-clock repository on GitHub, at the commit this page was made from: the board is csad10/CSAD10.kicad_pcb and its schematic csad10/CSAD10.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CSAD10 design in my own project?
Its repository states no licence, so its author keeps all rights: ask myriadrf before reusing the design.
