Challenges:
- I could not for the life of me get kicad working on my pc.
- I had a hard time making the pcb, but i got through.
- Holy let me tell you about how hard it was to find the xiao file, first i downlaoded it but it went in my documents, then in my D: drive??, and then it was in my Autodesk folder??

Questions
How big is the Hackpadv1 PCB?
It measures 76.2 × 98.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpadv1 use?
50 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 Hackpadv1 KiCad files?
From the adityasurendran/hackpad repository on GitHub, at the commit this page was made from: the board is PCB/hackpadv1.kicad_pcb and its schematic PCB/hackpadv1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackpadv1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask adityasurendran before reusing the design.
