README
README.mdTuenPiks
TuenPiks is a custom split keyboard built around a compact ergonomic layout, wireless operation, and a clean integrated hardware design.
This repository contains the hardware design files for the project, including the Ergogen layout source, KiCad PCB files, and fabrication-ready outputs for the board.
About
TuenPiks is a split keyboard with a vertically staggered ortholinear-inspired layout. It uses 12 columns in total, 5 rows, and a 3-key thumb cluster per half. The board is shaped with a tilted profile and designed for wireless use with a nice!nano v2, an OLED display, and a dedicated battery.
The goal of the project is to combine a compact split form factor with a straightforward, self-contained wireless build: controller, display, battery power, and switch support all integrated into the PCB design.
The repository includes two physical switch variants:
MX/for MX-spaced buildsCHOC/for low-profile Choc builds
Features
- Split ergonomic layout
- Vertically staggered ortholinear-style matrix
- 12 columns total
- 5-row layout with 3-key thumb clusters
- Tilted board shape
- Wireless nice!nano v2-based design
- OLED support
- Dedicated battery support with power switch
- MX and Choc variants
Design
The project is defined in Ergogen and developed further in KiCad for PCB layout and production-ready outputs. The checked-in design files include the board outline, key layout, switch footprints, matrix wiring, OLED support, battery connection, and power switching.
From the current files in the repo, the design includes:
- Layout definitions in Ergogen
- KiCad PCB projects for both variants
- Hotswap switch footprints
- Matrix diodes and row/column wiring
- nice!nano-compatible controller placement
- OLED connection points
- Power and battery connections

Questions
How big is the Splitty boy routed PCB?
It measures 142.6 × 125.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Splitty boy routed use?
118 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 Splitty boy routed KiCad files?
From the rmerli/TuenPiks repository on GitHub, at the commit this page was made from: the board is MX/Kicad/splitty_boy_routed.kicad_pcb and its schematic CHOC/Kicad/SplittyBoi_template.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Splitty boy routed design in my own project?
Its repository states no licence, so its author keeps all rights: ask rmerli before reusing the design.
