Questions
How big is the Coolpcbproject PCB?
It measures 90.9 × 38.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Coolpcbproject use?
28 parts, built around the ATMEGA32U4-AU and USBLC6-2SC6. 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 Coolpcbproject KiCad files?
From the fiction99/coolpcbproject repository on GitHub, at the commit this page was made from: the board is coolpcbproject/coolpcbproject.kicad_pcb and its schematic coolpcbproject/coolpcbproject.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Coolpcbproject design in my own project?
Its repository publishes it under the Apache-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).
