Questions
How big is the Alien PCB?
It measures 84 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Alien use?
51 parts, built around the LM324. 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 Alien KiCad files?
From the juanda/alien repository on GitHub, at the commit this page was made from: the board is alien.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Alien design in my own project?
Its repository states no licence, so its author keeps all rights: ask juanda before reusing the design.
