It measures 34.3 × 30 mm and has 2 copper layers, 1.6 mm thick.
24 parts, built around the AP63205WU and MCP3428-E/SL. 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 kamocat/pi_ups repository on GitHub, at the commit this page was made from: the board is pi_ups.kicad_pcb and its schematic pi_ups.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).
