Circuit diagrams and firmware source code for Gboard DIY keyboards

This is the files for my 3x3 key, oled, and rotary encoder macropad.
MacroPad pcb is an open-source printed circuit board by Sythe3911, from the Sythe3911/MacroPad repository on GitHub. It is a 2-layer board of 59.5 × 73 mm with 25 parts on 23 nets, routed with 96 tracks and 0 vias.
Its parts include 10 switches, 9 diodes, 1 IC and 1 connector. It belongs with the keyboards and input and lEDs and displays boards and the RP2040 boards of this library.
My MarcoPad is a 3x3 key, with a rotary encoder, and an OLED Display. It uses QMK firmware
Everything fits together using 4 M3 Bolts and heatset inserts. To keep the case and PCB together.
It has 2 separate printed pieces. One as the base acting as the bottum and sides and the other as a top.

Made in Fusion.
Here's my PCB! It was made in KiCad.

This hackpad uses QMK firmware for everything.
I might add more in the future! That's it for now

jes/scamp-cpu
A homebrew 16-bit CPU with a homebrew Unix-like-ish operating system.

It measures 59.5 × 73 mm and has 2 copper layers, 1.6 mm thick.
25 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 Sythe3911/MacroPad repository on GitHub, at the commit this page was made from: the board is PCB/MacroPad pcb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Sythe3911 before reusing the design.
