Project Details
My hackpad consist of 4 keys, a 0.91" OLED Display and two SK6812-MINI LED'S. Moreover, I am using XIAO RP2040. The case will be 3D printed while the the PCB will be printed and shipped by JLCPCB. I am going to hand solder all the componenets. PCB and Schematic Diagram is designed in KiCad while the Case is designed in Fusion360.

Questions
How big is the Hackpad PCB?
It measures 41.7 × 80.7 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 msafeerhassan/hackpad repository on GitHub, at the commit this page was made from: the board is kicadfiles/hackpad.kicad_pcb and its schematic kicadfiles/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 msafeerhassan before reusing the design.
