Overview
RoyBoard is an open-source printed circuit board by srxcode, from the srxcode/RoyBoard repository on GitHub, published under the MIT licence. It is a 2-layer board of 369.5 × 136.6 mm with 183 parts on 139 nets, routed with 1,108 tracks and 91 vias.
It is built around the SK6812MINI-E. Its parts include 90 diodes, 84 switches and 1 IC. It belongs with the keyboards and input boards and the RP2040 boards of this library.

Description
Its a mechanical keyboard that I made from scratch! Its basically a 75% tenkeyless keyboard with 81 keys in total, with 3 additional rotary encoders for different tasks such as volume control, brightness control and scrolling, of course these functionalities are subject to change. It has a few neopixels too! not per key RGB though, because i rarely use backlight and it was pretty daunting to route them up, considering the fact that i just started hardware back then, the ones which I have are meant for aesthetics. Currently, I have dropped the plan to solder them because I mirrored the pinouts and it will be a terrible mess to solder them, I guess I am still satisfied with how it turned out though.
Features
Includes RGB lights (not per key RGB)(Not soldered)- Has 3 rotary encoders for different functions
- Media playback
- Brightness
- Volume
- Scrolling
- DWM tag switching(Any other wm works)
- 2 Layer keyboard (as of now, may add more in future if needed)
- Consists of 81 keys in total + 3 clickable rotary encoders, a 75%-ish Tenkeyless keyboard
- 5 degree tilt stand for a comfortable typing experience

Renders
Just for reference, these are the original keycaps that I would be using: here . I changed the keycaps later on, thus the renders use a different keycap set.
Full 3d renders (To Be Updated)
The renders don't include stand yet, as it has been recently included. I will update the repo soon.

Questions
How big is the RoyBoard PCB?
It measures 369.5 × 136.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RoyBoard use?
183 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 RoyBoard KiCad files?
From the srxcode/RoyBoard repository on GitHub, at the commit this page was made from: the board is PCB/RoyBoard.kicad_pcb and its schematic PCB/RoyBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RoyBoard 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).
