Description
Dynamic decoration with LEDs and more
Hello everyone!
As you can see in the title, we have a circuit with LEDs, many LEDs, it's a 4x4 LEDs Cube. I've been planning to build such a dynamic ornament for a long time, the first step I took was designing this PCB. Totaling 64 5mm LEDs, the colors are your choice, distributed in a 4x4 matrix format (so 16 LEDs per layer, 2cm distance between LEDs) on 4 layers, it's a normal-sized cube, not very complex but which can be easily controlled using a board of your choice (Arduino, Rapsberry Pi and so on). I have blue LEDs, and I opted for blue color PCBs; we have the electronic diagram available, and on the PCB are noted the points where the fixing and interconnection elements (1mm wire diameter) of the layers will be soldered.
If you follow the circuit, you will easily figure out where the anodes and cathodes are placed on the PCB. Don't forget to put multiple pieces in your cart, gerbers only contain 1 PCB.
Like and comment with your thoughts. 🙂
Thank you and enjoy it! ✌

Hi! Those 5mm LEDs from LCSC.com are good. You can even use 3mm ones.
As for the 1-pin component, it's more of a graphic representation. You need a bridge between layers, about 4 cm distance between layers, use a 1mm thick wire, but it should be solid copper, not stranded. For example, you can search for it on the internet as 1mm copper rod/electrode.
We are not sure which one it is, could you provide a purchase link?
I use recovered materials, I make something myself. I can't find what I want at a store in my town.
Check this store (not from my country). The idea is to have a good, solid wire, 1mm diameter.

Thanks.The link you provided opens like this, is this normal?

There are two links, maybe you didn't distinguish them.Once again, it's a store outside my country.
Thanks. We got it.
You're welcome. 👍🙂
