Questions
How big is the Utf-8-samplified PCB?
It measures 40 × 107.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Utf-8-samplified use?
70 parts, built around the TL072 and PJ301M-12. 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 Utf-8-samplified KiCad files?
From the wgd-modular/utf-8-samplified repository on GitHub, at the commit this page was made from: the board is pcb/pcb.kicad_pcb and its schematic panel/panel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Utf-8-samplified design in my own project?
Its repository states no licence, so its author keeps all rights: ask wgd-modular before reusing the design.
