3 COLOR LED MODULE

[Djsarkar]

Hi,

I bought the 3 COLOR LED MODULE from aliexpress and i don't have any users manual documents I want to test 3 COLOR LED MODULE with 5v supply on bread board.

I have attached photo of 3 COLOR LED MODULE



I have not yet connected the power supply because I want to make sure proper connection

I did google and found the one link https://robu.in/product/dip-3-color...MI_cCjrIGa7AIVln0rCh39ZwUPEAQYCCABEgKaDfD_BwE

I am not sure that the module I have is the same the module given given in the link

Do I Need Current Limiting resistors?

How to check module with 5v supply?

Your module has current limiting 1 K ohm resistors built in.
You should have no problem in identifying the terminals.
Give +5 to the R, G, B terminals one by one, or any combination and the 0 V to the GND terminal
