I think Boncuk regards one of the five strips shown as 'a single module', whereas you refer to what is shown in the picture as 'a module'. Can you clarify whether there is 1 or 5 'modules' shown ??
WARNING: You must use a current-limiting resistor in series with the module(s), otherwise you risk destroying the LEDs.
It looks as though each strip has 3 white LEDs. Can you confirm?
If your supply is 12V then the maximum number of LEDs in series that you can power directly (i.e. without using a DC-to-DC converter) is 3.
