Heating controller – Triac board

Hi,

I successfully designed, etched and build triac board for my central & water heating controller.
Board is divided into two parts:

  1. Triac & optocoupler part
  2. Power supply part

 

Board features four BTA12 triacs that are driven by MOC3063 optocouplers and have snubber circuit. Optocouplers input will be controlled via MSP430 microcontroller.

Power supply part supplies 3.3V and 5V voltages to micro controller and WR703N Linux router. I decided to use low dropout regulators so that I can drive it from 6V transformer.
