Circuit diagrams and firmware source code for Gboard DIY keyboards

My first ever macropad project. In this project, I mainly follow the instructions from HackClub Blueprint and then add some modifications
Blueprintpcb1 is an open-source printed circuit board by ThongNQ867, from the ThongNQ867/Hackpad101 repository on GitHub. It is a 2-layer board of 100 × 56 mm with 18 parts on 24 nets, routed with 137 tracks and 12 vias.
It is built around the SK6812MINI-E. Its parts include 8 diodes, 6 switches, 1 IC and 1 connector. It belongs with the keyboards and input boards and the RP2040 boards of this library.
I have went back and update this hackpad with these changes:
Here is the PCB:

Here is the case:
BOM:

| 1 | XIAO-RP2040-DIP | Seeed Studio XIAO Series Library:XIAO-RP2040-DIP | U1 |
It measures 100 × 56 mm and has 2 copper layers, 1.6 mm thick.
18 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.
From the ThongNQ867/Hackpad101 repository on GitHub, at the commit this page was made from: the board is PCB/blueprintpcb1.kicad_pcb and its schematic PCB/blueprintpcb1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask ThongNQ867 before reusing the design.
