Questions
What parts does the Hardware UniversalRemote use?
58 parts, built around the CH340C, ESP32-WROOM-32U, HS0038BD and LM1117T-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.
Where can I download the Hardware UniversalRemote KiCad files?
From the qvinhdao/ESP32_UniversalRemote repository on GitHub, at the commit this page was made from: the board is Hardware_UniversalRemote/Hardware_UniversalRemote.kicad_pcb and its schematic Hardware_UniversalRemote/Hardware_UniversalRemote.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hardware UniversalRemote design in my own project?
Its repository states no licence, so its author keeps all rights: ask qvinhdao before reusing the design.
