Questions
How big is the Noise toaster PCB?
It measures 128 × 129 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Noise toaster use?
133 parts, built around the LM324, LM386, MMBT3904 and 1N4148W. 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 toaster KiCad files?
From the adeboni/eurorack repository on GitHub, at the commit this page was made from: the board is noise_toaster/pcb/noise_toaster.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Noise toaster design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
