Questions

How big is the Voicecard PCB?

It measures 236.9 × 126.6 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Voicecard use?

187 parts, built around the LM13700M, NE5532, CA3080A and BF244C. 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 Voicecard KiCad files?

From the icnagy/powertran-polysynth repository on GitHub, at the commit this page was made from: the board is voicecard/voicecard.kicad_pcb and its schematic P1-2/P1-2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Voicecard design in my own project?

Its repository states no licence, so its author keeps all rights: ask icnagy before reusing the design.
