Overview
KnowledgeBoard is an open-source printed circuit board by MrKnowledge9039, from the MrKnowledge9039/KnowledgeBoard repository on GitHub. It is a 2-layer board of 61.5 × 81 mm with 32 parts on 34 nets, routed with 243 tracks and 5 vias.
It is built around the SK6812MINI-E. Its parts include 20 diodes, 11 switches and 1 IC. It belongs with the keyboards and input boards of this library.

Hi! This is my submission for hackpad as part of stardance program! This was made for Hackpad v5 as part of stardance mission.
Overview
My very first hardware project: My own Macropad called KnowledgeBoard (I know very creative), completely designed by me, with 3x3 Keys, each with a SK6812 MINI-E and 2 Rotary Encoders as well as KMK firmware. I made it because I like learning new things. Multiple times I thought macro board would be very useful but I always worked around it instead of building one. And with the opportunity of Hackpad I wanted to try to build a macroboard that suits my needs. It should be compact, simple and at the same time versatile for different jobs like replacing a Streamdeck and improving the workflow with Krita or DMXC.
PCB

CAD
The Case Top and Bottom were designed using onshape. It helped that I had some experience in with 3D-Design. It was compared to that because I only used Extrude nothing complicated. Assembled are the separate case parts through screws.
Firmware
The firmware is KMK, because it seemed easier for this project then QMK and is pretty small but has every feature the board uses and supports multiple layers.
Notes
Making the pad was great and I will definitely progress doing also hardware projects. The Hackpad is a great starting point to get into this PCB/3D-Design.

Questions
How big is the KnowledgeBoard PCB?
It measures 61.5 × 81 mm and has 2 copper layers, 1.6 mm thick.
What parts does the KnowledgeBoard use?
32 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 KnowledgeBoard KiCad files?
From the MrKnowledge9039/KnowledgeBoard repository on GitHub, at the commit this page was made from: the board is pcb/KnowledgeBoard.kicad_pcb and its schematic pcb/KnowledgeBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the KnowledgeBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask MrKnowledge9039 before reusing the design.
