Questions
How big is the Solder PCB?
It measures 40 × 96 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Solder use?
40 parts, built around the BC337. 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 Solder KiCad files?
From the meeplabsdev/binary-converter repository on GitHub, at the commit this page was made from: the board is src/solder.kicad_pcb and its schematic src/solder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Solder design in my own project?
Its repository publishes it under the Zlib licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
