While the original Larva, designed by grezeh, is almost 3 years old, version 3 of the PCB of this Katana style symmetric keyboard was released just a few weeks ago.
Designed as part of a personal platform for research of combined, adaptable, extended Latin+Cyrillic keymap, it offers better ergonomics for day-to-day use when typing in multiple languages.
Keyboards, keymap, layouts are developed concurrently, work in symbiosis. I name the whole research project "mnemoNИk|Kombine" – grezeh.
The Larva PCB fits into the daisy 40% hhkb keyboard case by Kprepublic (coupon). The Mk.3 PCB outline is smaller, so it also fits the Poseidon/PSD40 case.
Changes
- Larva mk1 has 4 through-hole LED positions, no RGB, uses *AU MCU.
- Mk2 has 2 extra RGB SMD LED slots with up-facing SK6812MINI-E LEDs and 2 mono-color SMD LEDs, as well as "a few small QoL improvements".
- Mk2.1-light version gets rid of RGB and went open-source.
- Mk3: smaller outline to fit the PSD40 case, added one more bottom row option and non-stab option (without ISO enter).
