Dusk 36 Keyboard

Dusk 36 is a 36-key low-profile split ergo keyboard based off https://github.com/weteor/3W6 and https://github.com/davidphilipbarr/Sweep.

The Dusk 36 is designed around the nice!nano v2.0 microcontroller in order to be a true wireless keyboard (no cables between halves or from the keyboard to the computer). This board's layout was generated with my fork of Ergogen (which includes a few small changes), and then routed by hand in KiCad.
