Overview
TokeypadPCB is an open-source printed circuit board by Toki-dev465, from the Toki-dev465/Tokeypad-Macropad repository on GitHub, published under the MIT licence. It is a 2-layer board of 60.2 × 91.4 mm with 10 parts on 15 nets, routed with 69 tracks and 0 vias.
It is built around the SK6812MINI-E. Its parts include 7 switches, 1 IC, 1 diode and 1 connector. It belongs with the keyboards and input and lEDs and displays boards and the RP2040 boards of this library.

README.mdImportant Note
My PCB design has a slight error as the 5V on MC is connected to the VCC of OLED. Using 5V may or may not work. It could potentially damage the microcontroller and the OLED. Flashing QMK is a big pain hence I also made CircuitPython KMK firmware. Will definitely try the QMK firmware when I have time.
Description
IBM Model M keyboard themed macropad with a rotary encoder for volume control, 6 keys and a 0.91 inch OLED display.
Challenges
It was my first ever electronics project. First time using KiCad, Fusion and QMK. I spent many hours just trying to figure out how to do something by Googling and watching tutorials on YouTube. I had to redesign my schematics, PCB and 3D model numerous times. 3D modeling was much harder than I anticipated at first. Even though I made many errors, I believe this shows my learning progress because you can't learn without making mistakes.

Questions
How big is the TokeypadPCB PCB?
It measures 60.2 × 91.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TokeypadPCB use?
10 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.
Where can I download the TokeypadPCB KiCad files?
From the Toki-dev465/Tokeypad-Macropad repository on GitHub, at the commit this page was made from: the board is PCB/TokeypadPCB.kicad_pcb and its schematic PCB/Tokeypad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TokeypadPCB design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
