Questions
What parts does the EffectsPaddleBoard use?
107 parts, built around the TLV320AIC3100IRHBR, TPS54233D, B230 and RAPC10. 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 EffectsPaddleBoard KiCad files?
From the RK4444/EffectsPaddle repository on GitHub, at the commit this page was made from: the board is EffectsPaddleBoard/EffectsPaddleBoard.kicad_pcb and its schematic EffectsPaddleBoard/AFB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EffectsPaddleBoard design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
