Overview
Osu keypad version 4.0 is an open-source printed circuit board by lfscruuz, from the lfscruuz/keypad-design repository on GitHub, published under the MIT licence. It is a 2-layer board with 30 parts on 46 nets.
It is built around the ATMEGA32U4-AU and PRTR5V0U2X. Its parts include 9 capacitors, 6 resistors, 5 diodes, 2 switches and 1 IC. It belongs with the keyboards and input boards and the AVR (ATmega, ATtiny) boards of this library.

Questions
What parts does the Osu keypad version 4.0 use?
30 parts, built around the ATMEGA32U4-AU and PRTR5V0U2X. 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 Osu keypad version 4.0 KiCad files?
From the lfscruuz/keypad-design repository on GitHub, at the commit this page was made from: the board is osu_keypad_version_4.0/osu_keypad_version_4.0.kicad_pcb and its schematic osu_keypad_version_1.0/osu_keypad_version_1.0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Osu keypad version 4.0 design in my own project?
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).
