Circuit diagrams and firmware source code for Gboard DIY keyboards

This is a simple hack pad I made to learn PCB design and the basics of fusion 360.
Flightsimhackpad is an open-source printed circuit board by Zoomwag, from the Zoomwag/First-Hackpad-design repository on GitHub. It is a 2-layer board of 81 × 65.3 mm with 17 parts on 22 nets, routed with 212 tracks and 27 vias.
It is built around the SK6812MINI-E. Its parts include 8 diodes, 8 switches and 1 IC. It belongs with the RP2040 boards of this library.

I was inspired to mkae this project so that when you are playing a flight simulator you have acces to all of the most important buttons without ahving to reac acros your whole keyborad, It can aslo be used for FPS games as I designed it to incorperate a space for a wasd and a shift key. THis preject also allowed me to loearn the bacisc of pcb design and the basics of fusion 360.

It measures 81 × 65.3 mm and has 2 copper layers, 1.6 mm thick.
17 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 Zoomwag/First-Hackpad-design repository on GitHub, at the commit this page was made from: the board is hackpad PCB/flightsimhackpad.kicad_pcb and its schematic hackpad PCB/flightsimhackpad.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 Zoomwag before reusing the design.
