BTF-LIGHTING SK6812(WS2812B) RGBW LED Chips 100PCS RGB+Natual White Individually Addressable 5050SMD Module Pixels Light DC5V White PCB Chasing Dream Color for Christmas(No Adapter or Controller)

Worked exactly as intended. I wanted to create custom lighting for my 3D printer and was able to with these LEDs. I printed a mount, soldered them together, connected them to the printers main board, and wrote some code. Now I have white lighting while printing, red if an error occurs, and green once finished just for fun. They are individually addressable ass advertised which was convenient as I only have one header for this type of LED on my main board, the others would take some extra work to connect. This also made the wiring situation less hectic because I only needed one cable connected to the board instead of three. I’ve had them installed for a couple of weeks now and they have worked great, even when the temperature around them fluctuates more than normal. Overall a very solid purchase and something I will buy again for other projects once I inevitably run out of them.

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!

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".

Used these for backlighting a 3D printed model of the ship Event Horizon; 47 of these inside, controlled by a ESP32-C3 running WLED. Solder pads stick well and are sized nicely for wires. You do need to solder them all together, so if you're going to use an entire row, you will be doing jumper wires!

These LEDS are great for my project. Exactly as advertised and worked flawlessly. They are not wired together at all. They are just bare PCBs that need soldering and wire to work. These are not for everybody, especially if you're a beginner. These aren't breadboard compatible and need soldering to work out of the box, but if your project needs individual LEDS that require custom wiring then these are a great option. All 200 LEDS I ordered, I tested before and after soldering and they worked flawlessly. 4 stars because they need lots of soldering to work and they're use cases are way smaller than other led products.

Worked well for my project. They are bright enough to shine thru my PLA case.

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

I used these to add lights to a Star Wars Polar Droid project. The worked great.

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.
