samoklava

An autogenerated split 36 key keyboard

left	right

WARNING, for some reason the center thumb diode doesn't get wired automatically. You will want to open the generated files in Kicad and add the missing routes and repackage before sending off for fabrication (or just hand wire them in if you didn't catch it until you spent hours trying to track down all your bad solder joints only to find that one diode simply was not routed).

A 5x3 split keyboard with 3 thumbs. There is nothing unique about the keyboard layout. It's inspired by Corne and Kyria, and has the exact number of keys needed for the Miryoku layout.

The interesting thing about this keyboard is that it's a declarative design ("samoklava" can be loosely translated as "keyboard that assembles itself" from Russian).

• Layout is declared using Ergogen
• The build system uses Ergogen to translate YAML to a KiCad PCB and plate files for FR-4 fab or laser cutting
• uses kicad-automation-scripts and FreeRouting to automatically route the traces on the PCB
• uses KiKit to render PCB previews (see top of this file) and production-ready Gerber files

Features

• Extra pins and a slider switch for battery for wireless Promicro clones (tested with nice!nano v2); the slider can be shorted with a jumper if CONFIG_ZMK_SLEEP is preferred.
• Wired operation with QMK is possible (tested with OSOYOO Pro Micro Board ATmega32U4 Leonardo); TRRS footprints are included and routed. The pinout is identical with a five-column Corne sans the RGBLEDs.
• Reset switches are easily accessible. The footprints used are the same as on the Corne.

How to

If you would like to modify this:

• fork it
• change samoklava.yaml to your liking
  • use make clean design to see what your board looks like, images in design-output
• push your changes; the build.yml GitHub Workflow will pick it up, autoroute and generate Gerbers, all in a zip file. See https://github.com/soundmonster/samoklava/actions
• or:
  • make sure to have Docker CLI and NodeJS installed
  • run make setup clean all
  • check the output folder for KiCad PCBs and Gerbers
• buy the parts in the BOM.csv
• assemble
• flash both halves with ZMK (https://github.com/soundmonster/samoklava-zmk-config, or manna-harbour/miryoku#50)
• check all you keys
• start typing

See the workflow or the Makefile for more details.
