It measures 50.3 × 31.8 mm and has 2 copper layers, 1.6 mm thick.
13 parts, built around the B3B-XH-AM(LF)(SN), NC5FAH and NC5MAH. 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 second-string/xlr5-passthrough-breakout-hw repository on GitHub, at the commit this page was made from: the board is xlr5-passthrough-breakout-hw.kicad_pcb and its schematic xlr5-passthrough-breakout-hw.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
