Questions
How big is the Hackpad PCB?
It measures 94.5 × 53 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad use?
20 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 obobed/hackpad repository on GitHub, at the commit this page was made from: the board is hackpad.kicad_pcb and its schematic OPL_Kicad_Library-master/Grove Vision AI V2 Library/Grove - Vision AI Module V2.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 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).
