Circuit diagrams and firmware source code for Gboard DIY keyboards

I finally made the Macropad!
Spotify Macropad PCB Routing is an open-source printed circuit board by Insertmadface, from the Insertmadface/Spotify-Macropad repository on GitHub. It is a 2-layer board of 65 × 80 mm with 28 parts on 31 nets, routed with 284 tracks and 47 vias.
It is built around the SK6812MINI-E. Its parts include 17 diodes, 9 switches and 2 ICs. It belongs with the keyboards and input boards and the RP2040 boards of this library.
The Macropad here was designed with Ki-CAD for the PCB, and OnShape for the casing.

Final Picture of Routing
Desiged to control spotify via the app independently of main keyboard and without having the screen in focus.
4 M3 Heat-set Inserts
1 EC11 Vertical Rotary Encoder
8 Cherry-MX keyswitches with keycaps
1 SSD1306 OLED module
1 XIAO RP-2040 DIP
1 Custom Designed PCB :D
While designing, I used alot of resources, and I wanted to list them for anyone else
I had a ton of fun making this project and learned alot about so many things, from Heat-set inserts, to PCB design and even how to use github. I wanted to thank Hack-Club for making this opportunity available for teens around the world.

It measures 65 × 80 mm and has 2 copper layers, 1.6 mm thick.
28 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 Insertmadface/Spotify-Macropad repository on GitHub, at the commit this page was made from: the board is PCB/Spotify Macropad PCB Routing.kicad_pcb and its schematic PCB/Spotify Macropad PCB Schematic.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 Insertmadface before reusing the design.
