Overview
Pll is an open-source printed circuit board by fgl27, from the fgl27/pcb repository on GitHub. It is a 2-layer board with 24 parts on 25 nets, routed with 199 tracks and 18 vias.
It is built around the NE555, 74HC393D and 74HC86D, with the LM7805 among its other parts. Its parts include 9 resistors, 5 capacitors, 5 ICs, 2 diodes and 1 switch.

Questions
What parts does the Pll use?
24 parts, built around the NE555, 74HC393D, 74HC86D and LM7805. 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 Pll KiCad files?
From the fgl27/pcb repository on GitHub, at the commit this page was made from: the board is pll/pll.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pll design in my own project?
Its repository states no licence, so its author keeps all rights: ask fgl27 before reusing the design.
