Goga64 (aka Goga_OO) released the ULK, a 6 mm low-profile split keyboard with Corne 42 Layout and Cherry ULP switches. Made to be used on top of a laptop keyboard to provide the ultimate split experience on the go.
The batteries on the photos are not from the final design, but act more as a placeholder before the small batteries ship […] V2 coming in about a month with PG1316 support and solar charging for infinite battery life :) – Goga_OO.
Features
42 keys (6x3+3)
Cherry ULP or Kailh PG1316S switches, SMD
SuperMini NRF52840 (nice!nano V2 compatible)
power switch, reset button
ZMK firmware
Height: about 6 mm
This design is still under development and has some issues! Due to the availability of the ULP switches, only the clicky version was available which is nice for home, however, too loud for work at public places.
