Questions
How big is the Shady Pad PCB?
It measures 60.1 × 23.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Shady Pad use?
28 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 Shady Pad KiCad files?
From the samdoes-stuff/Shady_Pad repository on GitHub, at the commit this page was made from: the board is Design File/Shady Pad.kicad_pcb and its schematic Design File/Shady Pad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Shady Pad design in my own project?
Its repository states no licence, so its author keeps all rights: ask samdoes-stuff before reusing the design.
