So I got a bunch of these LEDs and I can't seem to figure out how to wire them. This is what I'm working with.

Back of the LED Front of the LED I tried adding the gnd and 5v but it doesnt do anything. When i connect the Din to 5v and Dout to gnd it blinks very weakly. I also cant seem to find any instructions for this specific model online. Thank you.

The LEDs you show are intended to form part of an addressable LED strip. You power via 5V and ground and then send a serial signal to Din. Normally the LEDs are connected in a chain with a LED's Dout (data out) connected to the next LED's Din (data in).

As they don't appear to have a clock line (just a data line) they are likely to be hard to drive from the Pi.

You need to identify the LED type, only then will you know how they can be programmed.
