# RK M75: reconstructing wired and wireless RGB control

> RK M75 reconstructs RGB control for the Royal Kludge RK M75 keyboard from wired USB HID captures and 2.4 GHz wireless experiments. A Python library sends per-key wired frames and grouped wireless frames; the repository also contains protocol notes, captures and a wired SignalRGB plugin.

## Requirements & limits

- **Prerequisites:** The documented hardware is an RK M75 with wired VID:PID 258A:0163 or wireless 258A:0148; development and hardware checks used Windows.
- **Prerequisites:** Python 3.10+ is required by the package.
- **Limits:** The wireless protocol is partial: arbitrary per-key colors and smooth 30 FPS streaming were not achieved.
- **License:** MIT license.
