Questions
How big is the Placa Definitiva PCB?
It measures 80 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Placa Definitiva use?
52 parts, built around the ADA4891-1ARJZ-RL, LM358, MCP4821-E/P and MAX9108ESD+T. 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 Placa Definitiva KiCad files?
From the KarimHacen7/ProyectoFinal repository on GitHub, at the commit this page was made from: the board is Placas/Placa Definitiva/v0.3/v0.3.kicad_pcb and its schematic Informe/circuitos/comparador op amp/comparador op amp.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Placa Definitiva design in my own project?
Its repository states no licence, so its author keeps all rights: ask KarimHacen7 before reusing the design.
