Questions
How big is the RFNoiseSource PCB?
It measures 70 × 31 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RFNoiseSource use?
58 parts, built around the LM317MDT and 2SC3356. 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 RFNoiseSource KiCad files?
From the profdc9/RFNoiseSource repository on GitHub, at the commit this page was made from: the board is RFNoiseSource.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the RFNoiseSource design in my own project?
Its repository states no licence, so its author keeps all rights: ask profdc9 before reusing the design.
