Questions

How big is the EMK310 P2 rev1 PCB?

It measures 80 × 100 mm and has 2 copper layers, 1.6 mm thick.

What parts does the EMK310 P2 rev1 use?

54 parts, built around the PIC18F45K22-E/P and LTS-6980HR. 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 EMK310 P2 rev1 KiCad files?

From the Boilingtub/EMK310 repository on GitHub, at the commit this page was made from: the board is KiCad/EMK310_P2_rev1/EMK310_P2_rev1.kicad_pcb and its schematic KiCad/EMK310_P2_rev1/EMK310_P2_rev1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the EMK310 P2 rev1 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).
