Zen Keyboard

A split ergo keyboard with a few goals in mind:

Be as thin as possible. Other split KBs (Let's Split, Nyquist, Iris) are 15.2mm thick. The Zen rev2 is only 13.2mm thick including switches and caps when using Kailh Choc low-profile switches, and 22.1mm using standard MX switches and DSA keycaps.
Layout designed for gaming. 1.5u pinky keys, ortho alphas, and angled thumb keys. After trying Ortholinear, Atreus62, and Ergodox, this is the best layout for gaming and typing.
Per-key RGB lighting. 34 WS2812b LEDs per side make it exceptionally bright
Price. Using Arduino Pro Micro, SK6812 LEDs, and PCB FR4 for the case, the cost of each half without switches or caps can be reduced to under $20 when purchased at volume.
Options. The Zen rev2 comes with rotary encoder support, SSD1306 OLED pinout, USB-C or TRRS interconnect, and jumpers to enable compatibility with the QMK Proton-C and the Keeb.io Elite-C

Keyboard Maintainer: Legonut Hardware Supported: Zen rev1, Zen rev2 Hardware Availability: RGBKB.net

A build guide and more info for this keyboard can be found here: Zen Build Guide.

Make example for this keyboard (after setting up your build environment):

make rgbkb/zen/rev2:default

To build for a Proton-C:

make rgbkb/zen/rev2:default CTPC=yes

Note: The Proton-C does not have split keyboard, or encoder support. Also OLED driver support is untested. Will update as status changes.
