Questions
How big is the 555 Emulation PCB?
It measures 80 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 555 Emulation use?
44 parts. 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 555 Emulation KiCad files?
From the ItBeNiro/555Emulator repository on GitHub, at the commit this page was made from: the board is 555_Emulation.kicad_pcb and its schematic 555_Emulation.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 555 Emulation design in my own project?
Its repository states no licence, so its author keeps all rights: ask ItBeNiro before reusing the design.
