Wireless split ortholinear keyboard with 70 keys, 2 nice!view displays, 2 rotary encoders.

Wireless split ortholinear keyboard with 70 keys, 2 nice!view displays, 2 rotary encoders.

Original inspirated by Sofle keyboard, but I want to add more keys (F-rows) and ortholinear layout. I also want to add 2 nice!view displays and 2 rotary encoders for better user experience.

- 70 keys - 2 nice!view displays (or 4pin OLED) - 2 rotary encoders (EC11) - Wireless connection (nice!nano or similar) with ZMK firmware support
