Questions
What parts does the Moco od501 use?
102 parts, built around the RT9013-33GB, TJA1050, CSD18540Q5B and NCP18XH103F03RB. 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.
Where can I download the Moco od501 KiCad files?
From the ziteh/moco repository on GitHub, at the commit this page was made from: the board is hardware/moco-od501/moco-od501.kicad_pcb and its schematic hardware/moco-bkd8316/moco-bkd8316.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Moco od501 design in my own project?
Its repository publishes it under the CERN-OHL-P-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).
