Questions
What parts does the Qynth PCB use?
15 parts, built around the H11L1, P120PK-Y25BR10K and 1N4148W. 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 Qynth PCB KiCad files?
From the BAbhiraman/Qynth repository on GitHub, at the commit this page was made from: the board is PCB/Qynth_PCB/Qynth_PCB.kicad_pcb and its schematic PCB/Qynth_PCB/Qynth_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Qynth PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask BAbhiraman before reusing the design.
