Questions
How big is the Smiler18 Direct PCB?
It measures 236.5 × 74 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Smiler18 Direct use?
20 parts. 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 Smiler18 Direct KiCad files?
From the weykn/Smiler18 repository on GitHub, at the commit this page was made from: the board is kicad/Smiler18_Direct.kicad_pcb and its schematic kicad/Smiler18_Direct.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Smiler18 Direct design in my own project?
Its repository states no licence, so its author keeps all rights: ask weykn before reusing the design.
