Befor. Im from Poland and im dont speak english very well , dont rate grammer :)

HI. there is my keyboard

I made this becuse i need keyboard. my actualy keyboard is 12 years: cosaco keyboard what i need use hot glue to repeir what.

it still work but Bro . you see how this look , i dont say its bad keyboard for me is fine but i wanna make something own what i be use for next years.

So there is my PKSBoard ( i dont have idea for name)

1776988882284-g3whwp

Note im finnaly dont use case becuse i dont have budget left for printing legion

It base on most simple things but becuse i wanna clean 65%+ i need to make Mcu and Key PCB separate on key pcb you dont see rp2040 its becuse i separte it and is why pick 2.54mm right angle , cable,

-MCU: RP2040-Plus , Everyone know wha t mcu is this.

-PCB: My own project , Is 65% size keyboard but i add Function button and Rotery Encoder Zrzut ekranu 2026-03-26 210054 old version Zrzut ekranu 2026-03-14 180553

-Switch: Akko V3 creamy blue is one of best budget switch on the world. its tactical so is silent but you fell click

-Keycaps. any random chepest keycaps what i can find to fit in budget

-Stablizators: for keycaps

-cable just cable there is cart

-Diods: i pick that becuse i have footprint only for this one

-Connector: to conect it its why is right angle there is cart from tme

Case: is simple case what i made in Fusion , im not skilled in this so is why is a simple.

Zrzut ekranu 2026-03-23 025524

i use programs:

Kicad: For PCB Autodesk fusion: For 3D modeling Paint: for diagram Google Docs: For BOM Cursor: for code

is all i spend aorund 20h on buldi this becuse i spend aorund 7h mcu what i finnaly dont buldi becuse cost. i have all in blueprint site so is why i dont have jounary here. finally my keyboard for me personal is good ( i be happy if it get aproved)

btw im pass this

there is one thing what left: BOM ( without link there, link verison is in folder)

Questions

How big is the Keyboard PCB?

It measures 308.9 × 117.9 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Keyboard use?

189 parts, built around the 1N4148W and WS2812B. 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 Keyboard KiCad files?

From the PriX-Y/Keyboard repository on GitHub, at the commit this page was made from: the board is Keyboard - leds version/Keyboard Kicad - Leds/keyboard.kicad_pcb and its schematic Keyboard - leds version/Keyboard Kicad - Leds/keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Keyboard design in my own project?

Its repository states no licence, so its author keeps all rights: ask PriX-Y before reusing the design.
