Overview
Hackpad is an open-source printed circuit board by QuantumKya, from the QuantumKya/RohansMacroPad repository on GitHub. It is a 2-layer board of 62 × 63 mm with 10 parts on 15 nets, routed with 47 tracks and 0 vias.
It is built around the SK6812MINI-E. Its parts include 5 switches, 1 IC and 1 diode. It belongs with the RP2040 boards of this library.

How I made it
I followed the tutorial on Hackclub's website! It was very good at teaching me the basics of everything! I kinda gave up for a few weeks before picking it back up again. I am working on my Summer of Making project at the same time!
I made a big mistake, and tried to submit the same thing as in the tutorial. I missed the part where it specifies that it must be something different, LOL. I fixed it all up pretty quick after that, though, spending two days making my own unique design and submitting it.

Questions
How big is the Hackpad PCB?
It measures 62 × 63 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad use?
10 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 QuantumKya/RohansMacroPad 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 QuantumKya before reusing the design.
