Overview
Keypad is an open-source printed circuit board by Azoto-liquido, from the Azoto-liquido/Multi-function-keypad repository on GitHub. It is a 2-layer board of 81 × 64.3 mm with 9 parts on 16 nets, routed with 121 tracks and 26 vias.
It is built around the SK6812. Its parts include 5 switches, 2 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.
Main components
1README
readme.mdMulti-function keypad
This is a 4 switches keypad with a rotary encoder and an OLED display, it has 2 LEDs and uses QMK Firmware.
I made it to learn a bit of this topic and I think it is perfect for general porpouse, everyday shortcuts and macros in gaming. Also in the little display you could write your name or a motd.

Cad
The 2 parts are held together with 4 M3x16mm SHCS Bolts without heatset inserts (the threads are cut directly into the plastic). The case has a 4 degrees titl for better ergonomics.
Made in Fusion 360.

Firmware Overview
The firmware uses QMK Firmware and is fully configurable with VIA.
- The rotary encoder serves as a volume controller.
- The 4 keys can be assigned to any key with VIAA (https://caniusevia.com/).
- Holding down the 4th key will activate another layer in which the keys can be assigned to any other function.
- The OLED display can be assigned to display any text (Always in VIA).
- The 2 LEDs can display any color (This is also done in VIA).

Questions
How big is the Keypad PCB?
It measures 81 × 64.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keypad use?
9 parts, built around the SK6812. 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.
Where can I download the Keypad KiCad files?
From the Azoto-liquido/Multi-function-keypad repository on GitHub, at the commit this page was made from: the board is pcb/keypad/keypad.kicad_pcb and its schematic pcb/keypad/keypad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keypad design in my own project?
Its repository states no licence, so its author keeps all rights: ask Azoto-liquido before reusing the design.
