Questions
How big is the LowNoiseDual5W PCB?
It measures 116 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LowNoiseDual5W use?
63 parts, built around the TPS62932DRL, TPS7A3301RGW, CL31A226MOCLNNC and B3B-XH-A. 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 LowNoiseDual5W KiCad files?
From the ulikoehler/PowerSupplies repository on GitHub, at the commit this page was made from: the board is LowNoiseDual5W/LowNoiseDual5W.kicad_pcb and its schematic LowNoiseDual5W/LowNoiseDual5W.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LowNoiseDual5W design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
