Inspiration
I've always wanted to build such hardware, and Hackpad gave me the perfect opportunity to start hardware creation
Challenges
This was the first time I used the XIAO library and Fusion 360. Although I did run into some issues, the tutorial helped me a lot as a beginner

Questions
How big is the Hackpad PCB?
It measures 41 × 62.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad use?
9 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 LegendPlayz83/Hackpad repository on GitHub, at the commit this page was made from: the board is pcb/hackpad.kicad_pcb and its schematic Bitstream/pcb/Bitstream.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).
