Questions
How big is the Pcb design PCB?
It measures 58.4 × 38.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Pcb design use?
27 parts, built around the ATMEGA328P-AU, CH340G and B5819W. 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 Pcb design KiCad files?
From the davidrihtarsic/davidrihtarsic.github.io repository on GitHub, at the commit this page was made from: the board is Projekti_iz_elektronike/Vsebine/Skripta_vaj/sheme_vezij/pcb_design/pcb_design.kicad_pcb and its schematic Elektronika/Skripta/sheme_vezij/Polvalni_usmernik_dioda.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pcb design design in my own project?
Its repository states no licence, so its author keeps all rights: ask davidrihtarsic before reusing the design.
