# Krtkus

An extended 5x12 keyboard with 2 extra keys. The design is intended for ortho layouts with a shifted number row, allowing for the placement of the delete and tilde keys above their usual spots. PCBs are designed in Kicad, case in Blender.

- Low profile

    - Kailh Choc V1

    - Gateron KS-27/KS-33

- QMK/VIA compatible

- Tray mount

- 3D printed case with a 7 degree tilt

To connect the keyboard to [usevia.app](https://usevia.app), the [design file](production/krtkus_design.json) has to be manually uploaded in the design tab.

## Room for improvement

- Spacebar stabilizer

- Hide MCU on the bottom side and use standard USB port orientation

- Get a better footprint for KS-33, the current one is very loose and hard to solder

## Parts

- One of the PCBs:

    - [Choc V1](production/pcb_choc_v1)

    - [KS-33](production/pcb_ks_33)

- Case: 

    - [STL file](production/krtkus_case.stl)

- Arduino Pro Micro

- 61 SMD diodes

- 61 switches

- 61 keycaps

Optional:

- 90 degree Micro-USB cable

- Rubber feet

## QMK

- Compiler: https://msys.qmk.fm

- Toolbox: https://qmk.fm/toolbox

On Windows, create a "krtkus" folder in `qmk_firmware/keyboards` and copy the contents of the [qmk folder](source/qmk) inside of it. Then in MSYS compile the firmware using the commands below.

Setup:

```

qmk setup

```

Compile:

```

qmk compile -kb krtkus -km default

```
