Questions
How big is the MediaPad PCB?
It measures 61.7 × 102.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MediaPad use?
54 parts, built around the SK6812. 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 MediaPad KiCad files?
From the Aahil78/MediaPad repository on GitHub, at the commit this page was made from: the board is src/MediaPad.kicad_pcb and its schematic src/MediaPad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MediaPad design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
