Questions
How big is the MiniSynth PCB?
It measures 50 × 40 mm and has 2 copper layers, 0.8 mm thick.
What parts does the MiniSynth use?
78 parts, built around the 74LVC1G3157, LP5907MFX-3.3, SMA6251A1-3GT50G-50 and DTC114Y. 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 MiniSynth KiCad files?
From the marcusmueller/MiniSynth repository on GitHub, at the commit this page was made from: the board is MiniSynth.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MiniSynth design in my own project?
Its repository states no licence, so its author keeps all rights: ask marcusmueller before reusing the design.
