Questions
How big is the Intro PCB?
It measures 301.2 × 110.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Intro use?
240 parts, built around the IS31FL3741A-QFLS4-TR and 1N4148W. 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 Intro KiCad files?
From the easymac/intro repository on GitHub, at the commit this page was made from: the board is intro.kicad_pcb and its schematic intro.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Intro design in my own project?
Its repository states no licence, so its author keeps all rights: ask easymac before reusing the design.
