Questions
How big is the 7segmentos PCB?
It measures 66 × 38.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 7segmentos use?
32 parts, built around the ATMEGA8-16AU, ULN2003 and SI2319CDS. 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 7segmentos KiCad files?
From the mathiasscroccaro/my_projects repository on GitHub, at the commit this page was made from: the board is 7segmentos/7segmentos.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 7segmentos design in my own project?
Its repository states no licence, so its author keeps all rights: ask mathiasscroccaro before reusing the design.
