Questions
How big is the Audio Visualiser DSP PCB?
It measures 100 × 100 mm and has 8 copper layers, 1.59 mm thick.
What parts does the Audio Visualiser DSP use?
401 parts, built around the CP2104EK, MCP6N11-001E/SN, MCP6024-I/P and MCP9804-E/MC. 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 Audio Visualiser DSP KiCad files?
From the drewsum/audio_visualiser repository on GitHub, at the commit this page was made from: the board is hdw/DSP_board/rev_a/Audio_Visualiser_DSP/Audio_Visualiser_DSP.kicad_pcb and its schematic hdw/DSP_board/rev_a/Audio_Visualiser_DSP/Audio_Visualiser_DSP.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Audio Visualiser DSP design in my own project?
Its repository states no licence, so its author keeps all rights: ask drewsum before reusing the design.
