Questions

How big is the AudioVis PCB?

It measures 76 × 115 mm and has 4 copper layers, 1.6 mm thick.

What parts does the AudioVis use?

13 parts, built around the OSTYK51102030 and XT60-M. 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 AudioVis KiCad files?

From the TerrenceCao1/AudioVisPCB repository on GitHub, at the commit this page was made from: the board is AudioVis.kicad_pcb and its schematic AudioVis.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the AudioVis design in my own project?

Its repository states no licence, so its author keeps all rights: ask TerrenceCao1 before reusing the design.
