this is a hackpad that i made to be more productive and to serve as a media player :)
I made this to learn about "professional" hardware and prototype making

Questions
How big is the Hackpad PCB?
It measures 100.5 × 43 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad use?
16 parts, built around the SK6812MINI-E. 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 Hackpad KiCad files?
From the Traffic-Person/hackpad repository on GitHub, at the commit this page was made from: the board is everything/hackpad.kicad_pcb and its schematic everything/hackpad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackpad design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
