Questions
How big is the Vocoder pico hardware PCB?
It measures 57 × 108 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Vocoder pico hardware use?
80 parts, built around the TL072, PCM5100APW, USBLC6-2SC6 and BC547. 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 Vocoder pico hardware KiCad files?
From the wehrend/vocoder-pico-hardware repository on GitHub, at the commit this page was made from: the board is vocoder-pico-hardware.kicad_pcb and its schematic display.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vocoder pico hardware design in my own project?
Its repository states no licence, so its author keeps all rights: ask wehrend before reusing the design.
