Circuit diagrams and firmware source code for Gboard DIY keyboards

This project is for a PQFP-100 adapter board designed using KiCad version 9.
PQFP-100 is an open-source printed circuit board by CodeAsm, from the CodeAsm/PQFP-100 repository on GitHub. It is a 2-layer board of 50.1 × 37.6 mm with 11 parts on 100 nets, routed with 477 tracks and 3 vias.
Its parts include 4 connectors and 1 IC.
This project is for a PQFP-100 adapter board designed using KiCad version 9.
in the release folder you may find a zip folder of the board gerbers ive send to production, a schematic and board overview in pdf format.
Here is an example use, but should work for most pqfp-100 chips (unless the pitch or pin size is way different)

As can be seen at the top of this readme, the below board has been produced at jlcpcb and the z80 ic functions. Below here you can see what it would look like in the 3d viewer. Its not specific to this ic, the pinout is one to one, 100 to 100.

Feel free to fork the repository and submit pull requests. For major changes, please open an issue first to discuss what you would like to change.
Id like to thank the following:

It measures 50.1 × 37.6 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 CodeAsm/PQFP-100 repository on GitHub, at the commit this page was made from: the board is PQFP100.kicad_pcb and its schematic PQFP100.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 CodeAsm before reusing the design.
