Questions
How big is the Noise pcb PCB?
It measures 50 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Noise pcb use?
70 parts, built around the 74HC164, 74LS86, CD4066BE and NE555P. 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 pcb KiCad files?
From the npaige751/synth_modules repository on GitHub, at the commit this page was made from: the board is lfsr_noise/noise_pcb/noise_pcb.kicad_pcb and its schematic clock/clock_panel/clock_panel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Noise pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask npaige751 before reusing the design.
