Questions
How big is the Main schematic PCB?
It measures 245.6 × 153.7 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Main schematic use?
248 parts, built around the ATMEGA168-20AU, AS6C6416-55TIN, ASEM1-100.000MHZ-LC-T and GTL2002D. 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 Main schematic KiCad files?
From the datamaskinprosjekt/PCB repository on GitHub, at the commit this page was made from: the board is main_schematic/main_schematic.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Main schematic 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).
