Questions
How big is the SmartDimmer PCB?
It measures 121.9 × 87.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SmartDimmer use?
93 parts, built around the BT138-600E, MOC3021M and ILD74. 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 SmartDimmer KiCad files?
From the dsankouski/SmartDimmerHardware repository on GitHub, at the commit this page was made from: the board is SmartDimmer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SmartDimmer design in my own project?
Its repository states no licence, so its author keeps all rights: ask dsankouski before reusing the design.
