67 Key ortholinear design, inspiration taken from the split design of the Sofle/Lily58 and Planck
-
33 keys per hand
-
1 Rotary encoder in the middle (Green)
-
Additional column positioned each side down the centre. (Orange)
-
Single microcontroller design while retaining characteristics of a split layout
-
130mm finger spacing while hands are at home positions (F/J keys) in a QWERTY layout. (Blue)
-
As there is no base plate by default, I've provided PCB files and laser cutting stencils which can be fabricated, if mounting on a plate you'll also require M2 standoff's and screws.
-
There is also a 3D printed case STL which fits the keyboard with the PCB resting on printed supports within the case, mounting screws not required.

(Optional):
| Part | Quantity | Description |
|---|---|---|
| LED Strip | 1 | WS2812 Compatible (30cm) |
| 3D printed case | 1 | 3D printed case, STL/gcode |
| PCB Base Plate | 1 | Bottom of case, covers underside |
| Base Plate Cutout | 1 | STEP file of base plate outline which can be laser cut |
- I have provided additional images here which show assembly.
- Place both stabalizers into the top plate
- Insert all switches into the top plate and put to the side
- Diode installation: Must be on the rear of the board due to lack of clearance from stabalisers.
- SMD mounting: Use smaller diode points marked below, ensure diodes are facing the correct orientation
- Through-Hole mounting: Use the wider spacing through-holes, ensuring diodes are facing the correct orientation.
- Snip off excess on top side.
- Reset switch: snip off legs before positioning on board.
- Place switch on top side of PCB and solder from underside
- Microcontroller needs to be positioned with the top of the board facing upwards (Test controller beforehand and flash firmware using QMK)
- Place the rotary encoder on the top side and solder all points ensuring it stays flush to the board.
- Press down the top plate with switches and stabalisers down on the middle plate ensuring that all the switches sit flush against the middle plate.
- Turn board over and proceed to solder switches to the board
- Connect USB to keyboard and check all keys are functional, this is assuming you've already flashed the firmware to the MCU.
