Overview
Win split left is an open-source printed circuit board by alexcamlo, from the alexcamlo/winsplit repository on GitHub. It is a 2-layer board of 426.4 × 120.4 mm with 331 parts on 144 nets, routed with 1,191 tracks and 238 vias.
It is built around the 74AHCT1G125SE and SRV05-4. Its parts include 146 diodes, 75 capacitors, 5 switches, 4 ICs and 3 resistors. It belongs with the RP2040 and AVR (ATmega, ATtiny) boards of this library.

Disclaimer
This is my first designed keyboard from the grounds up. I'm not responsible for any damage caused by using this keyboard or any production of this keyboard that doesn't work.
Bill of materials
To be bought separately:
- 2x RP2040 Pro Micro.
- 70x pin headers
- 1x Skyloong Rotary Encoder.
- 2x TRRS Connector.
- 2x SMD Buttons.
- 2x 128x32 OLED panels.
- 73x Kailh hotswap sockets.
- 73x SK6812MINI-E leds.
- 4x 2u Stabilizers.
- 16x M2 6mm screws.
Diodes, capacitors, resistors and other small parts are to be soldered directly by JLCPCB. References in KiCad files.
TODO
- Rotate 180º right-side OLED connector. Right now is not usable.
- Rotary encoder. As of now, it either works as a button when a normal switch is installed or as an encoder without button when the HS Skyloong encoder is installed.
- Make screw holes in PCB 4mm instead of 2.2mm. So they are passthrougth and bottom plate can be directly screwed to top plate, like lily58 or Corne keyboards.
Notes
- Function keys (Right of B and left of N) are hard to reach.

Questions
How big is the Win split left PCB?
It measures 426.4 × 120.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Win split left use?
331 parts, built around the 74AHCT1G125SE and SRV05-4. 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 Win split left KiCad files?
From the alexcamlo/winsplit repository on GitHub, at the commit this page was made from: the board is pcb/left/Win-split-left-backups/Win-split-left-2024-04-15_104843/Win-split-left.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Win split left design in my own project?
Its repository states no licence, so its author keeps all rights: ask alexcamlo before reusing the design.
