16 parts, built around the ATTINY1614-SSN, DS18B20 and TXB0102DCT(LX). 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 Pollex/MFM-Module-JSN-SR04T repository on GitHub, at the commit this page was made from: the board is hardware/jsnsr04t.kicad_pcb and its schematic hardware/jsnsr04t.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).
