Each BEEFASYER monitoring network is centered on exactly one Sparrow.
It measures 20.2 × 10 mm and has 2 copper layers, 1.6 mm thick.
8 parts, built around the BZT52C12 and RS3L110ATTB1. 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 medo64/SipMosRelay repository on GitHub, at the commit this page was made from: the board is src/SipMosRelay.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask medo64 before reusing the design.
