**********************************************************
************* Important Instructions Follow ************
**********************************************************
All files exported to: D:\Export_Storage\ExportBase\0\252274\Output\KiCAD\KiCAD\symbols.lib
After you have used Ultra Librarian to export library:
**************************************************
**To import your new library symbols into KiCad:**
**************************************************
1. Open KiCad.
2. On the program/tool list, go to Eeschema.
3. Select *Preferences* from the menu bar then select *Library*.
4. Click *Add* and choose the newly exported *.LIB* file.
5. You have now successfully imported your new symbol library!
**************************************************************
**To import your new library footprints/patterns into KiCad:**
**************************************************************
1. Open KiCad.
2. On the program/tool list, go to Pcbnew.
3. Follow the same steps as you would importing symbols, only this time select the *.kicad_mod* file.
4. You have now successfully imported your new footprint/pattern.
**************************************************************
** !!!!!!!!!!!!! WARNING !!!!!!!!!!!!! **
**************************************************************
KiCAD does not support filled/hatched polygons on footprints!
All polygons will be represented with an outline made of lines in each design.
Etch polygons will be drawn on the documentation layer, "Dwgs.User", and can be filled during board creation.

# Introduction #
This board is intended to serve as a dimmable controller for AC LED lights.
## Features ##
- As many channels as possible to fit in an equivalent board space to the 16 channel LED driver.
- 120V AC control with isolation.
- I2C interface
- Ability to add external zero crossing detection circuit to enable dimming.
- Reverse phase dimming
- Simple circuit design (with safety)
## Overview ##
I would like to use a low-cost stm32 part for the brains, running as an I2C slave. This would then output to several 74HC595 chips to drive the outputs. An external zero crossing detection signal would be used to enable reverse-phase dimming.
For the actual dimming and control, I will be using diode rectifiers with a MOSFET or an IGBT across each channel.
## Chips Used ##
