Questions
How big is the Print Project PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Print Project use?
249 parts, built around the TL431D, TIP140 and ZVN4306A. 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 Print Project KiCad files?
From the Gehtschon/pro3 repository on GitHub, at the commit this page was made from: the board is Print/Print_Project/Print_Project.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Print Project design in my own project?
Its repository states no licence, so its author keeps all rights: ask Gehtschon before reusing the design.
