Questions
How big is the FonteAssimetrica PCB?
It measures 67.3 × 67.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FonteAssimetrica use?
29 parts, built around the LM317, BC327, BC337 and TIP3055. 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 FonteAssimetrica KiCad files?
From the phckopper/fonte-introee-final repository on GitHub, at the commit this page was made from: the board is hardware-assimetrico/FonteAssimetrica/FonteAssimetrica.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the FonteAssimetrica design in my own project?
Its repository states no licence, so its author keeps all rights: ask phckopper before reusing the design.
