To split up a WS2811 data signal into discrete 5050 RGB 12V LED signals, I followed the example on the WS2811 datasheet and hooked up its outputs to a separate power supply.
This example shows one divider resistor on the red LEDs which is how I built my circuit. After doing research, I discovered that 5050 LED strips actually require a resistor for every color. So now I'm wondering if I built my circuit wrongly.
The 5050 LED strips are usually not very long, varying from 2 LEDs to 24 LEDs in total. Should I assume these components have their resistors built in already? Should I still add additional resistors and what value should they be? Or should I only add resistors to plain RGB LEDs which I will hook up?
Thanks in advance for any help!
Here's the electrical characteristics of the WS2811:
And here's that of the 5050 RGB spec:
