SparkFun Electronics will be closed on November 26, 2020 and November 27, 2020 for the Thanksgiving holiday. We will begin normal operations at 9:00 AM Mountain Time on November 30, 2020.
We know this looks like a lot of our other LEDs, but it's not! This is a PTH Addressable RGB LED with a WS2812 (or "NeoPixel") control IC built right into the LED. This PTH version is incredibly similar to its SMD cousin, except it is a lot simpler to solder into your project and is in a diffused 8mm package. This RGB LED has the control IC moved into the actual LED, so we wanted to offer this amazing product to you! They’re great when you need a lot of color from not a lot of board space, now more so than ever.
If you are looking for a great addressable LED in the more common LED form factor, then this is the perfect choice for you.
Note: Comes in packs of 5.
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

These worked perfectly with adafruits neopixel library, plus they were very cost effective. I had 48 of them linked in three strings for my infinity table. Here's the link if you want to see how they were wired or how bright they were: http://imgur.com/gallery/iUtkk
They are physically larger than I expected (not sure which part of 8mm I didn't understand when I bought them - reading is important) but they work great/as advertised/etc.
4/5 work perfectly, one died pretty quickly after sticking it first in a breadboard, then a PCB. It almost lights up if I attach VCC to the lead right below the cap, but dimly andv inconsistently. Less durable than a standard LED, but you get flashy colors.
I have used these as status indicators on several Microchip PIC based projects. Using a single data line I can have 2 or 3 full colour status indicators. Only issue is that the control timing in the datasheet is out-to-lunch, follow the timing in the hook-up guide or standard WS2812 timing. And, always put a small resistor (220Ω) between the CPU and the first LED.
