Up2stream Pro V3 RGB led

Hi everyone!

I’ml looking to use a rgb led to my proV3 but for now i can’t find the good wiring.
I tried this: Replicate Main LED on Bluetooth Amplifier Board with Wifi Up2stream Amp V4

But it isn’t working, i guess i need a different resistance.
Any idea?

So, i’m a little bit stuck. I found a non solution. I exchange de wiring and put the color to the 3v3 and the anode to a color and it’s working but… only for one color… So the rgb led is a kind of un useful…

Still looking for the solution…
