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

@toyman said in NModule DC Fan / PWM shield:
Can the FET withstand continious 2A load? I have one meter long 5050 strip
FDD8447L is rated for 15A continuous load. You don't want to try that because it's possible only with a big pad and 2oz copper PCB, but 2A will not be a problem on this board, there's plenty of margin

Hello Tilman, this is really a very nice design. I have ordered a pack of PCBs from elecrow, based on your gerber files, and have a few questions:
in your BOM you have listed 5 smd-capacitors and 7 smd resistors, but on the PCB i have solderpads for 6 capacitors and 8 resistors. Can you just explain?
is there a uniflächentaster-model for 2 ways?
i think i have to flash the bootloader first, do you have a tutorial for this, and a sample-sketch for the board?
Thank you very much
@JahFyahh - I still haven't managed to et round to it. I've been really busy since this project and its still hectic here. I'm sure i read a few reviews somewhere, here or google. Not sure.
