FYI...
12v = Mosfet = irlz44n, Voltage Reg (12 to 5v) = LM2940CT-5
24v = Mosfet = ???, Voltage reg (24 to 5v) = ???I think IRZL44N will handle 24V.
@xydix thanks! This was on my to-do list to find out but it's great with a helpful community!

Cool. What MYSX version is used?

@anticimex Well - its 2.4 header (mostly for stability) but its only actively 2.1 which is used so Im not sure.

In your next rev, perhaps you increase the spacing between the voltage regulator and the MOFSET to accommodate heat sinks? The minimum would be 2.54mm.
@simbo sure! I was thinking only the mosfet would need a heatsink so my plan was to attach it on the back. The maximum led strip I have is 2.5m and I didn't have to use any heatsink so didn't think much about it. Do you have some sort of heatsink link you prefer (with measurements) I can have a look at.

Hi, some -maybe- silly questions:
In the diagram you marked MysX connector number 9 as the "LED1", but that's the A5, and not the D3 where I see it is connected. (just asking this to be sure that I understand right the board, and the diagram)
So this is only a typo, right?Other question is that I can use the mysensors LED dimmer example sketch with the rotary encoder with this board, right? It needs 4 digital pins, and MysX has 4: "D2, D3, D5, D6".
So I just have to replace in the sketch the #define KNOB_ENC_PIN_1 4 to #define KNOB_ENC_PIN_1 2?
"#define LED_PIN 3 // Arduino pin attached to MOSFET Gate pin
#define KNOB_ENC_PIN_1 4 // Rotary encoder input pin 1
#define KNOB_ENC_PIN_2 5 // Rotary encoder input pin 2
#define KNOB_BUTTON_PIN 6 // Rotary encoder button pin" -

Im not sure where you get that #9 should be A5? Looks right to me. The pin is connected to pin 9, and that is D3.
For a rotary encoder, it depends on your input - but don't you want an analog signal in? In that case you use the analog pins.
Edit: offcourse, if you use a module converting it to digital like described in the the build section you use a digital pin.
