12 parts, built around the MKL03Z16VFK4 and LM1117-3.3. 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 fitzdoingprojects/kinetis_boards repository on GitHub, at the commit this page was made from: the board is MKL03Z16VFK4/kicad/MKL03Z16VFK4.kicad_pcb. 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).
