I guess I got what I paid for purchasing something with no reviews.The one that does work is great but 2 of the 3 in the package are junk. They will power up and attempt to show what is being output to them but will flash all kinds of random stuff. At first, I went chasing ghosts in the wiring only to take the one from the breadboard that was working and put it into the project after trying the other 2. If it weren't for the fact that I needed this working now, I would return these but that's really not an option at this point so I will trash the 2 bad ones and hope the working one doesn't fail.Definitely would not recommend these to anyone.

The boards appear to have even solder application and properly mounted components. I hooked them to a nodeMCU board project of a scale car speedometer to test. The lights were bright and responsive. Great buy!

Out of 2 lots(10pcs) ONLY TWO WORKED. The white ones worked. A few of the color ones partially lit random segments But we're not functional. Most of them the only light was the power led on the back. I agree with the other review. I wasn't paying attention, to reviews..I needed them fast..The first one I grabbed out of lot 1 just happened to work(white). So I ordered the 2nd lot. This was a mistake.
