Questions
How big is the Noise generator PCB?
It measures 57.2 × 38.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Noise generator use?
21 parts, built around the LM324. 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 Noise generator KiCad files?
From the restelli/noise_generator repository on GitHub, at the commit this page was made from: the board is kicad/noise_generator.kicad_pcb and its schematic kicad/noise_generator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Noise generator design in my own project?
Its repository states no licence, so its author keeps all rights: ask restelli before reusing the design.
