Questions

How big is the Pegasus kicad PCB?

It measures 242.9 × 76.2 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Pegasus kicad use?

111 parts, built around the ATMEGA32U4-MU. 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 Pegasus kicad KiCad files?

From the melonbred/open-source-projects repository on GitHub, at the commit this page was made from: the board is keyboards/pegasus/kicad/pegasus_kicad.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Pegasus kicad 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).
