Questions
How big is the Synth PCB?
It measures 153.6 × 153.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Synth use?
69 parts, built around the MCP6002-I/P, MCP6004-E/P and SE555P. 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 Synth KiCad files?
From the DJ027X/simple_synth repository on GitHub, at the commit this page was made from: the board is synth/synth.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Synth design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
