Questions
How big is the ProtDimmer PCB?
It measures 76.2 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ProtDimmer use?
22 parts, built around the BT137, EL817, MOC3021M and BC548B. 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 ProtDimmer KiCad files?
From the MateoCignetti/ProyectoFinal repository on GitHub, at the commit this page was made from: the board is Prototipos/Dimmer #1/KiCAD/ProtDimmer/ProtDimmer.kicad_pcb and its schematic Prototipos/Boost #1/KiCad/boost_converter/boost_converter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ProtDimmer design in my own project?
Its repository states no licence, so its author keeps all rights: ask MateoCignetti before reusing the design.
