Questions
How big is the Estagio versão2 PCB?
It measures 171 × 114 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Estagio versão2 use?
152 parts, built around the MD-90S. 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 Estagio versão2 KiCad files?
From the roneitstone/Internship-PCB repository on GitHub, at the commit this page was made from: the board is estagio-versão2.kicad_pcb and its schematic estagio-versão2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Estagio versão2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask roneitstone before reusing the design.
