Questions
How big is the Synthesizer PCB?
It measures 68.9 × 59.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Synthesizer use?
48 parts, built around the BCW31 and CONSMA006.062-G. 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 Synthesizer KiCad files?
From the gsuckz/pll repository on GitHub, at the commit this page was made from: the board is kicad_pcb/synthesizer/synthesizer.kicad_pcb and its schematic kicad_pcb/power_supply/power_supply.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Synthesizer design in my own project?
Its repository states no licence, so its author keeps all rights: ask gsuckz before reusing the design.
