Questions
How big is the Src4392 PCB?
It measures 76.8 × 56.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Src4392 use?
84 parts, built around the PIC16F18056-I/SS, 74LVC1G17Z, PLR237/T10BK and FIN1047M. 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 Src4392 KiCad files?
From the schenkmi/electronic-projects repository on GitHub, at the commit this page was made from: the board is dac-pcm1702-v1/kicad-asrc-v13/src4392.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Src4392 design in my own project?
Its repository publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
