    Yup.. Checked those & everything is where it should be. I'll pull out my reflow station tomorrow and make sure I didn't miss a solder spot. However, I went over everything with a magnifying glass before I hooked it up.

    Did you install 33pF caps? If yes, remove it from one of the boards.

    I did install the 33pF capacitor on all of them...

    I removed one from a board and I still get the same results... Blue light instantly comes on when its when plugged in. I've also bypassed the ESPixelStick and get the same results.

    Another thing I noticed is that the color shifts around a bit. Sometimes its blue, white blue, magenta blue.. etc. It changes at random times. It doesn't matter if its connected to a controller or directly to power.

    Did you cut off the connecting tang, gnd side of the rgb led ?

    Each gnd leg should be individualized .

    Yup.. all 3 pins are free and connected properly. The LED is also in the correct position (anode side closest to the resistors... just like the wiki says)

    I've gone over all 3 of the boards i built, I just can't find anything wrong with them. Well.. other then the dont work

    Sorry to bug you... but did you have a chance to check out my photos? I really wanted to use these on the 20th for a party we are having. I may have to go a different route and just trash these
