15 parts. 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 AtomicCali/ElectroTactileDigitalBrailleReader repository on GitHub, at the commit this page was made from: the board is KiCad/ETDBR_SingleDigitV1/ETDBR_SingleDigitV1.kicad_pcb and its schematic KiCad/ETDBR_MultiDigitControlV1/ETDBR_MultiDigitControlV1.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).
