A STM32F103-based USB PWM fan controller for PCs with RGB/ARGB lighting support (Windows 11 Dynamic Lighting).
[!WARNING] 🚧🚧 PROJECT UNDER CONSTRUCTION 🚧🚧 – use at your own risk.
Please refer Hardware Readme for pinouts and more info.
Control lighting from Settings -> Personalization -> Dynamic lighting (effects, brightness, color).
[!Note] Only Windows 11 Dynamic Lighting tested so far. Effects on other platforms are not guaranteed.
Conrtols using FanControl is recommended.
Install both FanControl and FanControl.USBreeze plugin, and you're good to go!

It measures 76.1 × 57.2 mm and has 2 copper layers, 1.6 mm thick.
151 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the mr258876/USBreeze repository on GitHub, at the commit this page was made from: the board is Hardware/ProPrj_USBreeze_2026-02-05.kicad_pcb and its schematic Hardware/KiCad/ProPrj_USBreeze_2026-02-05.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask mr258876 before reusing the design.
