PRINT CODEX — DEVIL BREAKER

EVERY MARK TELLS YOUR CODE.

Devil Breaker Print Codex turns DarkBeacon's one-handed TMR platform into a dedicated control surface for your Codex workflow.

Game with 0.001 mm TMR precision, Rapid Trigger, and adjustable actuation in regular mode.

When it's time to build, switch on Codex Mode and put threads, approvals, navigation, voice input, and essential Codex actions directly under your left hand.

Built for control. Printed for Codex.

Small Form. Full Control.

CODEX AT YOUR FINGERTIPS.

Turn Print Codex into a dedicated control surface for your Codex workflow.
Switch threads, approve changes, navigate, dictate, and send—all from the keyboard.

YOUR THREADS. ONE PRESS AWAY.

6 Agent Controls. Live Status.
Jump between Codex threads and see their status through RGB indicators.

Made for the Codex Workflow.

The Print Codex visual system carries its developer-focused identity across the keyboard, with dedicated legends designed around the actions you use when working with Codex.

The included Codex keycap set gives you additional options for adapting the physical layout to your preferred workflow.

Feel Every 0.001 mm of Control.

HUANO TMR sensing detects extremely small changes in key travel, giving you finer control over every press and release.

Tune your actuation points with greater precision, reset inputs with less movement, and execute fast repeated actions with greater consistency.

Move Faster. Reset Instantly.

Rapid Trigger dynamically resets a key as soon as upward movement is detected instead of waiting for it to return to a fixed reset point.

That means faster repeated inputs, sharper direction changes, and more responsive movement when every fraction of a second matters.

Your Trigger Point. Your Advantage.

Adjust each key's actuation point from 0.01 to 3.5 mm.

Choose a shallow actuation point for faster reactions or a deeper press when you want more deliberate input.

Tune individual keys around the way you play.

One Key. Multiple Actions.

Assign multiple actions to different stages of a single keystroke.

Trigger different commands as you press, hold, or release a key, giving you more control without adding more keys to your layout.

Your Keyboard. Your Rules.

Fine-tune actuation, configure Rapid Trigger and advanced key functions, remap controls, build macros, customize RGB lighting, manage profiles, and configure Codex Mode through DarkBeacon.AI.

Every key can be configured around the way you work and play.

Describe It. Watch It Glow.

Tell DarkBeacon.AI the colors, movement, or atmosphere you want.

AI Lighting transforms your prompt into a custom RGB effect, making it easy to create a lighting style that matches your setup—or your mood.

Swap Switches. Keep Playing.

Hot-swappable sockets make replacing TMR magnetic switches simple with no soldering required.

Maintain your keyboard more easily and keep it ready for every session.

Compatible with DarkBeacon original switches only.

Soft Texture. Deeper Glow.

Single-sided frosted translucent keycaps combine a soft matte top surface with clearer side walls.

The layered construction diffuses RGB light across the keys while allowing a brighter glow to shine through the sides.

Light Beyond the Keycaps.

A dedicated side light strip extends the RGB glow beyond the keys, adding more depth and atmosphere around the keyboard and across your desktop setup.

HONEYCOMB BACK DESIGN.

A geometric honeycomb pattern adds depth and structure to the back of the keyboard, extending its technical, industrial character beyond the keycaps.

From the top surface to the underside, every angle is designed to feel unmistakably Print Codex.

Everything Within Reach.

The focused 30-key one-handed layout keeps essential controls inside a tighter movement zone.
Customizable keys add more command options, while the control knob provides fast access to frequently used functions.

In Codex Mode, those same physical controls can become part of your Codex workflow.

LET YOUR CODE GLOW

Per-key RGB and side lighting shine through the translucent keycaps, bringing the Print Codex visual system to life.

Change the colors.
Change the atmosphere.
Make the workspace yours.

Built in Layers. Tuned for Control.

A gasket mount structure, layered foam, switch pad, and acoustic materials help isolate vibration and reduce unwanted resonance.
The result is a softer, more controlled key feel with improved typing acoustics.
