This is a LED strip dimmer and Power shield using the MysX standard in MySensors.org.
Just like a shield on a Arduino or Raspberry PI you can add features on your MysX compatible PCB/node by just adding this shield. In my case I wanted an easy way to attach a LED power supply and drive a dimmable led strip. I will add this to my Easy/Newbie PCB as a shield. The Easy PCB will act as the MySensors brain (communication with controller and dim level output) while the LED board will handle the power and led.
This board have a input for your LED strip power supply (Normally 12-24v). On the board you can add a Mosfet which will be controlled by PIN3 on the MysX connector. You also have a resistor in series (see your mosfet datasheet in needed). When adding your power supply for the led strip you can choose to let this power supply drive the VCC pin and the motherboard as well. This way you can avoid dual power supplies. Be sure to regulate down the power with a voltage regulator (TO-220 package) and add capacitor for smoothing the power.
Build the board according to BOM. Make sure you choose the right Mosfet and Voltage regulator for your power supply. Example:
More instructions will come when tested.
