Overview
Splitkeyboard v2 is an open-source printed circuit board by Anycircle11139s, from the Anycircle11139s/Splitkeyboard-v2 repository on GitHub. It is a 2-layer board of 312.1 × 113.7 mm with 142 parts on 109 nets, routed with 1,083 tracks and 121 vias.
It is built around the S2B-PH-K-S(LF)(SN). Its parts include 60 diodes, 4 resistors, 4 ICs, 2 connectors and 2 switches. It belongs with the keyboards and input boards and the nRF52 and nRF5x boards of this library.

The second attempt of creating the prefect split keyboard by @NotALarp
WHAT IS IT?
This is my custom split keyboard made in KiCad, based on a LILY58 split keyboard design, it is sleek and is designed with ergonomics in mind.
Featured Hardware:
- Nice!Nano v2 microcontroller
- Lipo batteries
- Low profile choc switches
- 0.91" OLED displays
- EC11 Rotary Encoders
WHY I MADE IT
My first split keyboard was pretty bad, it was based on a xiao nrf58240 microcontroller, had a terrible layout and overall wasn't that good. So I decided that with my previous knowledge that I would create a new, second split keyboard.
NOTES AND DESIGN CHOICES
This time I decided to base the layout on a real split keyboard and some better microcontrollers. I decided on the nice!nano v2 and based the layout on a Lily58 split keyboard which I think looks really good. I designed a custom, 3d-printed case which was created to be compact, modern and sleek.

Questions
How big is the Splitkeyboard v2 PCB?
It measures 312.1 × 113.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Splitkeyboard v2 use?
142 parts, built around the S2B-PH-K-S(LF)(SN). 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 Splitkeyboard v2 KiCad files?
From the Anycircle11139s/Splitkeyboard-v2 repository on GitHub, at the commit this page was made from: the board is Split keyboard v2/Split keyboard v2.kicad_pcb and its schematic Split keyboard v2/Split keyboard v2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Splitkeyboard v2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Anycircle11139s before reusing the design.
