Jorne is officially suppored by ZMK, see https://zmk.dev/docs/hardware. I recommend SuperMini as a wireless controller.

• ZMK firmware wiki: https://github.com/joric/nrfmicro/wiki/Software
• QMK firmware wiki: https://github.com/joric/qmk/wiki/jorne

There is the official config for Jorne (clone the repo to rebuild and download artifacts, or get firmware.zip from releases):

Upd. Jorne firmware is a part of ZMK now, newest firmware is here: https://zmk.dev/docs/hardware

RGBTOG currently toggles VCC as well (CONFIG_ZMK_RGB_UNDERGLOW_EXT_POWER=y). There's no sleep mode or lock shortcuts in ZMK just yet, sleep mode as automatic (15 minutes).

• Raise + Lower + ~ Turn RGB and OLED off (essentially turns off VCC, key matrix still works)
• Raise + Lower + Shift Reset Bluetooth bonds
