Questions
How big is the Hd2 PCB?
It measures 108 × 93 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hd2 use?
62 parts, built around the PIC18F4620-E/P, MAX232N, 74HC595 and DS1307Z+. 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 Hd2 KiCad files?
From the Danjovic/FreeHD300 repository on GitHub, at the commit this page was made from: the board is circuit/hd2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hd2 design in my own project?
Its repository publishes it under the GPL-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).
