Circuit diagrams and firmware source code for Gboard DIY keyboards

My first PCB project. This is a macropad that I will use to when coding with VSCode in order to make it a more efficient and effective experience.
Vspadproject is an open-source printed circuit board by bukhariayan, from the bukhariayan/vspad repository on GitHub. It is a 2-layer board of 59.2 × 77.1 mm with 11 parts on 14 nets, routed with 105 tracks and 8 vias.
Its parts include 6 ICs, 2 diodes and 1 switch. It belongs with the keyboards and input boards and the RP2040 boards of this library.
This is my first PCB project. It is a macropad that I will use when coding with VSCode in order to make it a more efficient and effective experience. I haven't yet decided exactly what command each key will do, so the code may be edited in the future.

It measures 59.2 × 77.1 mm and has 2 copper layers, 1.6 mm thick.
11 parts. 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 bukhariayan/vspad repository on GitHub, at the commit this page was made from: the board is PCB/vspadproject.kicad_pcb and its schematic PCB/vspadproject.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 bukhariayan before reusing the design.
