Questions
How big is the Dsp PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dsp use?
47 parts, built around the LM358N, NCP1117ST and PMEG2005EH. 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 Dsp KiCad files?
From the cillian64/blueboxes repository on GitHub, at the commit this page was made from: the board is dsp/dsp.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dsp design in my own project?
Its repository states no licence, so its author keeps all rights: ask cillian64 before reusing the design.
