20 parts, built around the PCN-105D3MHZ,000. 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 fabXlabs/SpeedyAdapterPCB repository on GitHub, at the commit this page was made from: the board is speedyAdapter.kicad_pcb and its schematic speedyAdapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
