Questions
How big is the Proiect1 PCB?
It measures 40 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Proiect1 use?
39 parts, built around the BC846, BC856 and 1N4148W. 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 Proiect1 KiCad files?
From the tcfh2003/Proiect_CEF2 repository on GitHub, at the commit this page was made from: the board is PCB_project/Proiect1/Proiect1.kicad_pcb and its schematic PCB_project/Proiect1/Proiect1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Proiect1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask tcfh2003 before reusing the design.
