Keychron K5 Max ISO RGB (QMK) — Solid background with afterglow effect (VIA)

This repository contains a QMK firmware build for the Keychron K5 Max featuring a custom RGB matrix effect. A changeable solid background color with a reactive afterglow on keypress. Capslock and Numlock are kept on if active.

It is VIA-enabled, so you can remap keys and adjust supported lighting parameters through VIA.

Usage

The effect can be selected using the RGB-Mode keys on the keyboard, but it won't show up in the VIA effects list.

• Hue controls the background color.
• Brightness controls the background intensity.
• Saturation controls the color of the afterglow.
• Speed controls the duration (how long the afterglow persists).

---

Build

Use make keychron/k5_max/iso/rgb:via to build the firmware. To flash the firmware, setup your keyboard in cable mode, run make keychron/k5_max/iso/rgb:via:flash, disconnect the cable and reconnect it while holding ESCAPE.

VIA

This firmware is built with VIA support enabled.

• Use VIA to change key mappings.
• Use your usual QMK/VIA lighting controls to adjust hue/brightness/saturation/speed and see the effect respond.
