The 104 most common of 120 parts.
It measures 160 × 100 mm and has 2 copper layers, 1.6 mm thick.
120 parts, built around the LMZ23605TZ, BSS84 and ZPD15. 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.
From the thainnos/ICSscannerDiode repository on GitHub, at the commit this page was made from: the board is hardware/networkScanner.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
