What is this project
This is a split keyboard. It is divided into 2 parts. I designed it to gain some experience in pcb design, cad modeling and firmware development. It has 22 keys per side, oled display, and rotary encoder.
Why I made it
I want to design my own keyboard to gain experience in hardware project. I got a lot of useful information about creating schematics, pcb routing, footprints, cad case modeling and file structure on github.

- split keyboard pcb
- cad case
- firmware file
- gerber files

3D Model
Full Keyboard Assembly
IMAGE COMMING SOONN AFTER BUILD...
this is the complete 3d model of the split keyboard with all major components placed inside the design. the model was created to verify the fit of the pcb, switches, display, rotary encoders, and case before manufacturing.
Firmware
the firmware files for this project are available in the split_keyboard_firmware/ folder.
currently the firmware is still being developed and tested. basic project structure, display examples, and source files have already been added to the repository.
build notes
- i used kicad for my schematics and PCB design
- i designed the keyboard case in cad
- i exported gerber files for manufacture
- i kept the design simple to make it easy to build and code
BOM
note
this project is still being worked on, and i will keep improving the case, layout, and code.

Questions
How big is the Split keyboard kicad PCB?
It measures 230.5 × 167.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Split keyboard kicad use?
104 parts. 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 Split keyboard kicad KiCad files?
From the AYUSH-pro-grammer/split-keyboard repository on GitHub, at the commit this page was made from: the board is kicad/split-keyboard-kicad.kicad_pcb and its schematic kicad/left.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Split keyboard kicad design in my own project?
Its repository states no licence, so its author keeps all rights: ask AYUSH-pro-grammer before reusing the design.
