Questions
How big is the CSPS PCB?
It measures 95 × 40.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CSPS use?
41 parts, built around the TLV70433DBVR, AO3400A and SMAJ24A. 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 CSPS KiCad files?
From the paulc/csps-pcb repository on GitHub, at the commit this page was made from: the board is CSPS.kicad_pcb and its schematic CSPS.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CSPS design in my own project?
Its repository states no licence, so its author keeps all rights: ask paulc before reusing the design.
