Questions

How big is the Lampo PCB?

It measures 54.8 × 57.2 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Lampo use?

38 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 Lampo KiCad files?

From the Az154za/Lampolite repository on GitHub, at the commit this page was made from: the board is PCB/lampo.kicad_pcb and its schematic PCB/lampo.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Lampo design in my own project?

Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
