I have published all the documentation in a Github repository. If someone wants to make PCBs, I recommend that you wait a little longer until you receive my PCBs and try them.

The node is a very simple one. So I never considered boot loaders, as the node would not need changing sketches during it's lifetime. I have boot loading functionality on my other designs, this one is a minimal board. Any extra chip would beat the purpose of the word "minimal".
It's a dumb node for a reason

Hi krisztian,
the singleLED board - as its name suggests - features only one LED output. If you want to have a setup with multiple LED strips you need to design a board with multiple outputs. I have already designed a board with 4 outputs, but I haven't built it.
In terms of software you need to register multiple sensors in your program like this:
#define numCh 4 //the number of outputs
const byte ledPins[] = {9,6,5,3};
byte ledLevel[numCh];
boolean ledDimWay[numCh];
//in the setup function request the dim levels from the gateway
for(byte i=0; i<numCh; i++) request(i, V_DIMMER);
//in the presentation function register multiple lights
for(byte i=0; i<numCh; i++) present(i, S_DIMMER);
//if you receive a signal, you need to check for the sensor id
setLED(message.sensor, requestedLevel);
//to set the LED level (function: setLED) you need to use the sensor id to determine brightness and pin
//Fade LED to set level
int delta = (level - ledLevel[child]) < 0 ? -1 : 1;
//Write to LED
analogWrite(ledPins[child], map(ledLevel[child],0,100,0,255));
I will probably publish the whole code once I have built and tested the 4LED controller (i call it "MySensors rainbowLED")
Hope I could help you

I have finally gotten back to this project and created a working sketch that communicates with my Vera controller. I have this set up as a 3 button on/off (6 switches on the board) and have that working successfully with Vera. I also have my Vera sending temperature data back to the OLED display. It alternates between the outside temp and room temp for my master bedroom where the switch is located. I have posted the Arduino sketch under source code here.
