Questions
How big is the Pcb PCB?
It measures 71 × 69.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pcb use?
12 parts, built around the NE555P. 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 KiCad files?
From the SHALINISATHISHH/pcb repository on GitHub, at the commit this page was made from: the board is pcb.kicad_pcb and its schematic pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask SHALINISATHISHH before reusing the design.
