I seem to have missed this altogether and here, years later I find this thread by accident searching LOL

Thanks a ton for this info, would you mind terribly showing me how to wire these up in series ?
The above diagrams look like they are both in parallel :)

The output of this board is designed to drive LEDs directy (FET outputs), but maybe they could drive the PWM board as well.

I just need the low level DMX to PWM output to run the drive circuit. Do you think this could be adapted to that use. A shot in the dark here.
Thanks

https://www.xmas-land.de/30-channel-DMX-512-Controller-circuit-board#false

30-channel DMX decoder for controlling our RGB-LEDs, RGB LED strips or modules via DMX-512. The decoder can process the standardized DMX-512 protocol. Three channels (red, green, blue). The power supply and the RGB LEDs are connected via screw terminals. The DMX control cables can be connected via the XLR-3 or RJ45 socket.

The DMX-512 controller has internal test programs that are selected as well as the DMX address via DIP switches

The DMX-512 signal is referenced to the same board ground as 12V power.
The DMX-512 is based on RS-485, so it is not sensitive is there is some noise or small potential differences on the ground wires when they carry the current.

I have myself one decoder board.

You are purely the only one who has written anything on this card.
I bought 3 of these cards and before doing any damage, I wanted to ask you if I can use a common 12 v power supply, or if I have to use a special power supply for LED lights.
I thank you in advance.
