Questions

How big is the PSU LowNoise PCB?

It measures 60 × 69.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the PSU LowNoise use?

48 parts, built around the BC547 and GBU2506. 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 PSU LowNoise KiCad files?

From the cybaer/PSU_LowNoise repository on GitHub, at the commit this page was made from: the board is HW/PSU_LowNoise.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the PSU LowNoise design in my own project?

Its repository states no licence, so its author keeps all rights: ask cybaer before reusing the design.
