Low-pro 36-key hot-swappable monoblock split ortho keyboard with optional Pimoroni trackball support.
Production Files
To place an order for the Haori36 PCB:
- Use the gerber files in the production/ folder.
- Optionally one can utilize the BOM and CPL files with a PCBA service to avoid manually soldering SMD diodes, which can be challenging to solder by hand. All components are soldered to the bottom side of the board.
The complete PCB project is in the kicad/ folder.

There are multiple options for the plate:
- 3D print using the STL file (or the no-trackball version).
- Adjust the tolerance settings as needed. As a reference, I set the
Initial Layer Horizontal Expansionto-0.3mmand theHorizontal Expansionfor subsequent layers to-0.1mm.
- Adjust the tolerance settings as needed. As a reference, I set the
- Use PCB material with the plate gerber files, and opt for
1.6mmor2.0mmPCB thickness. - Laser cut with the DXF file.
The folder also contains an editable STEP file for customization.
Firmware
The Haori36 comes with precompiled VIA-enabled firmware, with trackball enabled by default:
- Flash penk_haori36_via.uf2 to the RP2040-Zero.
- Load the via.json file in
Designtab for VIA configuration.
Default Keymaps
The firmware source is located under firmware/QMK/. The trackball settings can be adjusted in rules.mk and config.h.

Questions
How big is the Haori36 PCB?
It measures 204.3 × 68 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Haori36 use?
79 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 Haori36 KiCad files?
From the penk/Haori36 repository on GitHub, at the commit this page was made from: the board is kicad/haori36.kicad_pcb and its schematic kicad/haori36.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Haori36 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
