Questions
How big is the AudioSpectrumLED PCB?
It measures 41.9 × 72.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AudioSpectrumLED use?
18 parts. 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 AudioSpectrumLED KiCad files?
From the MTRNord/AudioSpectrumLEDGrid repository on GitHub, at the commit this page was made from: the board is Hardware/AudioSpectrumLED.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the AudioSpectrumLED design in my own project?
Its repository publishes it under the AGPL-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).
