BTF-LIGHTING WS2812B 100PCS 5050SMD Individually Addressable Smart RGB LED Pixel for Arduino Single 1-led RGB LED Module Pixels Color Light White PCB Only DC5V Christmas(No Adapter or Controller)

These are fantastic! They are small, about the size of a penny, so they require some dexterity to work with. I use a helping hand to hold them for soldering though and it is no problem. They work brilliantly! I have driven them so far using a Raspberry Pi 3, an Arduino Uno and a Nano. In all three cases they were great, bright, nice color and very responsive. I bought a 5v 15amp power supply to power them, but I have also plugged them directly into the 5v rail of my EVGA G2 1300 watt psu as well and they worked no problem. Keep in mind that all 100 of these at full brightness will draw a lot of amps, way too much for your USB port, so a power supply is a must. Soldering is pretty easy. They are small, but the pads are ample enough, there are 6 total, 2 for 5v, 2 for ground and 2 for data in and out. That is 600 solder points for the whole lot! I have had the best success using single strand 20 AWG hookup wire. I tried some stranded 4 pin wire I had for regular rgb led's, but it became brittle and snapped off at the solder points when handled too much. I picked up some 18 AWG 3 pin cable as well, but it is stranded cable and can be a pain to solder. SIngle strand cable has been the easiest for me by far. I am enjoying these a lot and will be buying lot's more!

In the 144 I soldered into strings, there was not a single dud. These rock!

These are very bright, colorful, and very responsive. Make sure you buy a good driver for it. dont go cheap cheap. They really work great with a good driver.

These worked great! Ordered these for a 3D project and will order again.

Awesome lights! Perfect for my project! The colors look great!

I think these little LED Pixel's are a pretty good value. None of them have failed after a couple of months, and getting them set up was pretty easy. 3-wire in 3-wire out, soldering them is pretty straight forward that being said, if you are not used to soldering very small things on PCB's you may need to practice before you can get a clean solder on them

I have a 3D printer and I'm a software engineer. These little dots are fantastic for little RGB LED based projects. Some of those hobbyist web stores sell Neopixel LEDs for $5 for 10. These are a bargain, and the pads on the back are much easier to solder than just a bare chip or the flex-pads on the strips of LEDs. I've probably used 50 of the 100 so far and they have all worked. No "duds".

Easy to solder but must use 24awg or thicker when using multiple bulbs to allow current flow. So far so good. Next time I will get the ones with the white built in I accidentally ordered the wrong ones but they are cheap and easy to interface using the arduino neopixel library.

Awesome lights for projects requiring custom LED work. Small little buggers to solder though! Six solders per led is a lot, so hopefully you don’t require too many for each of your projects. Awesome with using FAST LED Arduino library and an ESP8266 board. Happy DIY’ing!!!

Prodotto di nuona fatturra, qualche led ha problemi di in/out(ma su 100) non è un grosso problema. Fanno una luce molto intensa nella foto ho le finestre aperte ed entra luce eppure sembra buio con questi led. I led sono SINGOLI devono essere saldati, non sono strisce led. Funzionano perfettamente con la libreria adafruit neopixel in Arduino IDE. Io gli consiglio, sono ben fatti e funzionano perfettamente. Ottimo rapporto qualità prezzo.

Place these anywhere and just run the 3 wires in and out great for different effects

Intente hacer prender e hice varios arreglos y ninguno prendio

Many of the LEDs are broken. 60 %. Luckely I only needed a few.
