README.mdInspiration
I created this macropad so that as the name suggests, chill. I wanted to be able to do things quick and easily by using shortcuts through the macropad.
Challenges
This was my first time using autodesk fusion, and my first time ever designing a PCB! Even though at times I struggled with extruding sketches and routing the PCB, I went through the tutorial and got a LOT of help from people on the slack.

Questions
How big is the Hackpad PCB?
It measures 52 × 99 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad use?
8 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 shreeyuvan2020/Chilled repository on GitHub, at the commit this page was made from: the board is PCB/Hackpad.kicad_pcb and its schematic PCB/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 states no licence, so its author keeps all rights: ask shreeyuvan2020 before reusing the design.
