The Story of Project
In short, this project is the result of a challenge. One day, a friend who was visiting me, saw my experiments with some led matrix and ask me if I can control many of these. I answered "yes certainly", using auxiliary integrated circuits can be controlled a large number of LEDs.
I started doing research and after I saw many projects I have concluded I need a ready-made panel and start my experiments from there. Also I wanted to skip monochrome panels and try with multicolor LEDs.
I observed that RGB panels are a little more expensive than dual color panels (the price difference is noticed especially when you plan to buy many).
So I decided to start with this panel: http://www.gearbest.com/development-boards/pp_65373.html which I think would best fit my future plans.
Priced at $ 13.91 is the best price that I could find (at the time I made the order).
I must say that this panel is why I "landed" at this store in the first place. Meanwhile I made several orders (from "Development Board" section)... and I will return with other articles if I manage to do interesting things with them.
The panel came as a kit. I guess that panel is used to make large displays available as finished product at some specialized vendors/manufacturers.
However, this panel assembly requires soldering of many SMD components. This requires careful planning of the sequence in which components will be soldered.
In the next steps I will show sequence that worked for me.
