Questions
How big is the Board555 demo PCB?
It measures 21.9 × 34.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Board555 demo use?
7 parts, built around the NE555D. 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 Board555 demo KiCad files?
From the Epivaral/Sessions repository on GitHub, at the commit this page was made from: the board is Introduccion a diseno PCB/board555_demo/board555_demo.kicad_pcb and its schematic Introduccion a diseno PCB/board555_demo/board555_demo.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Board555 demo design in my own project?
Its repository states no licence, so its author keeps all rights: ask Epivaral before reusing the design.
