Attention
- The USB-Library is licensed under the SLA0044 License and therefore incompatible with the GPL. Until this is resolved the GPL does not apply to the "Firmware" folder.
TODO
- Finish PCB
- Currently working on a barebone blue pill
- Probably remove the option for two different µC options
- Replace USB Lib
- Implement Rust version as a learning experience?
- But currently USB hates me :/
- Replace the USB lib to be compatible with an open source license
Features
- Connection for 18 fans
- 3 Fans form one group
- 6 independently controllable
- only one fan in each group reports rpm
- 3 pin fans are supported but not regulated (I tried it, but ended but beeing to complicated since I plan on using 4 pin anyways)
- 4 thermistor inputs
- compatible with the corsair commander pro driver of the kernel
- Compatible with the "blue pill" boards or an stm32f103c8tx in an LQFP48 package
- The goal is to make is easy to solder and LQFP48 can be hard

Questions
How big is the OpenFanHub PCB?
It measures 100 × 93.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the OpenFanHub use?
120 parts, built around the AMS1117, USBLC6-2SC6, AO4409 and IRLML2502. 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.
Where can I download the OpenFanHub KiCad files?
From the koskev/OpenFanHub repository on GitHub, at the commit this page was made from: the board is Hardware/openfanhub/openfanhub.kicad_pcb and its schematic Hardware/openfanhub/fan_connector.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the OpenFanHub design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
