SMD LED - RGB WS2812B (Strip of 10)

The WS2812B (or “NeoPixel”) may look like a common 5050-sized (5x5mm) SMD LED, but there’s actually an integrated control circuit embedded inside there too. If you look really hard, you can see the tiny black chip hidden in there, along with minuscule gold wires connecting the chip to the LED. This LED is certainly more than meets the eye! The ‘B’ at the end of the WS2812 name denotes that these specific LEDs are equipped with and only require FOUR pins instead of SIX!

The LED itself is unlike most RGB (Red/Green/Blue) LEDs. The brightness of each color can be adjusted using a serial string to one of 256 different levels. That means there are 16,777,216 (2563) possible combinations of colors. You can produce any color from white to black (off), or salmon to sienna.

  • Viewing angle: 120 degrees
  • Red: (620-625nm) @ 390-420mcd, 2.0-2.2V
  • Green: (522-525nm) @ 660-720mcd, 3.0-3.4V
  • Blue: (465-467nm) @ 180-200mcd, 3.0-3.4V
  • 4-pin Design

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

3 Soldering

Skill Level: Competent - You will encounter surface mount components and basic SMD soldering techniques are required.
See all skill levels


Core Skill: Programming

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.

2 Programming

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.

Core Skill: Electrical Prototyping

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.

3 Electrical Prototyping

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.

Customer Comments

  • just how long is the strip? it says that 5x5mm stip of ten but i’m new to this hole electronics tinkering world. and can anyone be so kind as to tell me if and how i can connect a bunch of these strips together? and yea i know lots of Q- but can i cut the strip if needed to desired length? like i said i’m new at this so try not to go hard on me when replying or commenting lol.

    • This is not a ready to go strip. These are individual LEDs that come on a tape and reel. We are cutting off lengths of 10 and selling them, but they still need to be soldered into your circuit. For ready to go strips check out some of our other ws2812 parts.

  • BT / about 3 years ago * / 1

    Lame product description… To use these you connect them in a serial string and shift brightness and color information into them (as outlined in the docs). You don’t have direct control of (or need to worry about) forward voltage or PWM for brightness.

  • Why do you have Forward Voltage for a chip that runs TTL data input.

Overall great product!

These LEDs were easy and fun to work with! The only downside to working with such small LEDs, and other small components as well, is the pins ended up being very fragile. After soldering, be very careful with handling the LEDs. The solder joint was stronger than the pins themselves. On 4 of my LEDs, the Din pin snapped off because of an accidental tug on the wire that was soldered to it. I guess that’s the trade-off for having small components, however.

Great LED's, no soldering information

Once you get these running, they’re the cats ass for sure. I embed these in all sorts of projects. The only issue I have is during the reflow process. I use solder paste and a reflow oven and I have failures, 2 in 10 (firing a standard reflow curve). I then use my hot-air rework to drop in replacements. I e-mailed Adafruit about this a while ago, and they said their supplier said they needed to be tempered before reflowing? Never heard that term before. Can you offer any advice Sparkfun?a

Used on several projects and they're great!

They’ve been very reliable and worked consistently. I’ve purchased over 200 of them for projects and never had any troubles.

What COLOR these create

I was really impressed with the colors these modules created, just so vibrant they are mesmerizing.
