Simple `PT4115`-BreakoutBoard, initially designed for my special 490 nm LED but may also be used for generic projects
Evolved from a "Simple `PT4115`-BreakoutBoard" we now have a full blown electronics and software project!
If you want to know more about `CyanBus`, `CyanLight`'s new animation protocol suite on top of `RS485` just goto [the documentation of SiliconTorch](SiliconTorch/README.md) !
`CyanLight` now stands for the complete light and animation system which I'm developing for my appartement.
Pinout
It consists of multiple hardware and software layers with a possible full stack-up looking like this from the bottom upwards:
------
Pinout of the companion board `CyanLightControl`. All external general purpose IOs are protected against ESD and negative reverse voltage input.
-`CyanLight v[10W].1` - `PT4115` board (LED current control)
-`CyanLightControl` - `ESP32` board outputting some `PWM` signals
-`SiliconTorch[C++]` - `ESP32` firmware implementing protocols like `CyanBus` and `FxCyanF`
-`CyanBus` - `RS485` serial protocol for packetized data streaming
-`FxCyanF` - `LED` animation protocol
-`CyanBusInjector` - `Ethernet` to `CyanBus` bridging board
-`SiliconTorch[PY]` - High-Level device control via `Python`
| GPIO | Function |
The last mentioned layer would then run on some SBC in a drawer and do the animation rendering. But what if this is not the end?

Big things are on the way! Source-less animation building coming soon™!
