Overview
This my very first project on KiCAD and my firt ever harware project. It is inspired by the tutorial over blueprint. There are 6x1u switch and 1 2u switch with 1 Rotary Encoder. There will be my acrylic sheet b/w the space just over XIAO.

Questions
How big is the Finale PCB?
It measures 97.6 × 88.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Finale use?
24 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 Finale KiCad files?
From the SummerHigh18/MessedPad repository on GitHub, at the commit this page was made from: the board is PCB/Finale.kicad_pcb and its schematic PCB/Finale.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Finale design in my own project?
Its repository states no licence, so its author keeps all rights: ask SummerHigh18 before reusing the design.
