From the todbot/TS20_Test_Board repository on GitHub, at the commit this page was made from: the board is schematics/TS20_Test_Board/TS20_Test_Board.kicad_pcb and its schematic schematics/TS20_Test_Board/TS20_Test_Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
