CyanLight
Simple PT4115-BreakoutBoard, initially designed for my special 490 nm LED but may also be used for generic projects
If you want to know more about CyanBus, CyanLight's new animation protocol suite on top of RS485 just goto the documentation of SiliconTorch !

Pinout
Pinout of the companion board CyanLightControl. All external general purpose IOs are protected against ESD and negative reverse voltage input.
