Questions
How big is the Noisesource psu PCB?
It measures 65 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Noisesource psu use?
45 parts, built around the FT230XS-R, TPS61175PWP, TPS22917DBV and SS14FL. 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 Noisesource psu KiCad files?
From the dkozel/noisesource-psu repository on GitHub, at the commit this page was made from: the board is pcb/noisesource-psu.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Noisesource psu design in my own project?
Its repository states no licence, so its author keeps all rights: ask dkozel before reusing the design.
