Questions
How big is the Freesample PCB?
It measures 124 × 190 mm and has 8 copper layers, 1.6 mm thick.
What parts does the Freesample use?
577 parts, built around the OKL-T/3-W12P-C, ADP1741ACP, HMC675LP3E and LM27761DSG. 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 Freesample KiCad files?
From the azonenberg/freesample repository on GitHub, at the commit this page was made from: the board is boards/freesample/freesample.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Freesample design in my own project?
Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
