Questions
How big is the PreAmp PCB?
It measures 68.3 × 46.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PreAmp use?
30 parts, built around the INA217AIDWR 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 PreAmp KiCad files?
From the TimWannet/Hardware_Vocoder repository on GitHub, at the commit this page was made from: the board is Hardware/KiCad/PreAmp/PreAmp.kicad_pcb and its schematic Hardware/KiCad/Main_Board/I_O.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PreAmp design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
