Help with 3444 8 x 8 Matrix

by CanadaLEDNewb on Wed Jun 16, 2021 5:30 pm

Hi,

I just got a 8 x 8 Dotstar matrix and it comes with a capacitor. Do I need to use it or not and if I do I attach the long leg to the Positive, correct?

I'll be running the LEDs from a Pixelblaze or a NodeMCU running WLED

Thanks,

Adad

The capacitor smooths any current surge when the strip (it's really just a 64 DotStar strip electrically) is first powered on. It's recommended that you add it. The longer of the two leads should be the positive one which gets connected to 5v, the other is connected to ground. More conclusively, the negative side will be marked with a distinctive white stripe which usually has minus signs on it.
