Questions
How big is the Guitar dsp platform PCB?
It measures 122 × 122 mm and has 4 copper layers, 1.59 mm thick.
What parts does the Guitar dsp platform use?
168 parts, built around the ESP32-DEVKITC-VE, PCM3060PW, TPS5402D and OPA2156ID. 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 Guitar dsp platform KiCad files?
From the ShrapnelDSP/ShrapnelPCB repository on GitHub, at the commit this page was made from: the board is guitar_dsp_platform.kicad_pcb and its schematic analogue.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Guitar dsp platform design in my own project?
Its repository states no licence, so its author keeps all rights: ask ShrapnelDSP before reusing the design.
