WS2812B RGB IC Addressable 16x16 256 Pixels LED Matrix DC5V

I had some trouble getting this display going. Using an Arduino Mega and some sample code found online, I ended up with just 1 LED coming on. When I reached out to the manufacturer, they were responsive and offered a wiring diagram to assist. They also mentioned that 1 LED lit often means no data connection. I verified solid connections and when that still didn’t work, the manufacturer offered to send a remote controller to use for testing. It was then that I realized I had switched data with ground. Duh. If only I looked at that after the support engineer mentioned it... Once I made the proper connection the unit worked well. Bright, rich colors. This is my first experience with an LED matrix, but if need to by another, I wouldn’t hesitate to purchase this one again. TL;DR: Good customer service Nice matrix display Would buy again

I got two of the 8x32 version, and i must say the quality is impeccably good for both of them. Both were packaged very well and even include a extra 3 pin connector, which is nice, and both were totally clean and undamaged when they arrived. These things are ridiculously bright even at low power levels, like I can light up my whole room at just 5% brightness bright, even with just the output of a Arduino Uno! They are also very easy to use, only really needing care not to accidentally send more then 5V into them, otherwise it's almost as easy as plug-and-play. Definitely a very great LED array, far better then most of the other ones I have seen around the same price. I recommend using a external power source though, these things really can pull a lot of volts and amps at higher brightness!

These LED panels are pretty awesome and I highly recommend them, especially when hooked up to the SP107E controller (Note the following though.) 1. Set the SP107E controller to GRB, WS2811 (I know it is different but the only one which works) 32 Segments x 8 Pixels per segment. 2. The wattage says up to 76.8 watts so I bought a big PSU. When I tested it though it can use much much less power and still be bright enough in a room that is very well lit / or bright with daylight. I found the minimum wattage to only use 1.9 to 2.1 watts even with the controller, and at a very good brightness about 7 watts. Yes it will go up to the maximum wattage if you push it but that is not needed at all. I am running two panels now for 512 pixels and use an average of 3 to 3.8 watts (this is measured at 120V input to PSU) total with controller in daylight.

I used the 8x32 256 pixel panels and gave these 11x44 panels a try. These panels are very nice, I was able to display using the Adafruit libraries, they displayed correctly, but only could display 5x7 fonts? I tried configuring other fonts, but wasn't able to get it to display correctly. Perhaps if I can figure it out and give it a try again. These are nice...I had two panels end to end so it was 11x88...968 WS2812B...

Arrived quickly and carefully packed. Used at first with Arduino nano to make a sign for my car's windshield for Uber and Lyft. Very , very bright. I have installed behind 90% tinted window film and still is very bright during daylight time. I have used the same foam box included to mount on windshield after painting it black Now I got the controller from BTF and works great too. I will provide a separated review and video for it.. The quality of the 8X32 matrix is Excellent and less than half of price from other brands. I have ordered multiple units. BTF customer service is the best with replies in just hours and not days. Now I am planing to create a pool RGB matrix with multiple units

I bought this about a year ago for a project and although I never finished the project, the 44 x 11 LED array worked great! It's very bright, easy to connect up to any WS2812-compatible controller (or Arduino). I used mine with an Advatek PixLite controller. I plan to purchase more of these arrays to build a larger sign as the only down-side to this array is the size. For my application, I wish the LEDs were spaced further apart and the overall array was larger. Cost is a little high, but if you're in need of more than a couple you should be buying in bulk from China

My guess is that these things have been sitting around for too long and maybe just went bad after being exposed to probably too much heat or something. I got one and only about 2/3rds of the LEDs would light up, they also wouldn't respond to the Arduino code correctly. The code works fine on other WS2812B LEDs so whatever maybe just bad luck. I got a replacement shipped to me and this time they all do light up, however again they don't respond correctly and just seem to do their own thing. I checked my code again and used a bunch of random code(specifically for these kinds of matrixes) off the internet that also doesn't work with this thing. But guess what? The code works just fine with my other WS2812B LEDs. Either the posting here is wrong or there is a pretty bad QC issue with these things nowadays. Now I have 2 pieces of garbage that I need to ship back on my own time before I can even get a refund. Fun. Don't buy, there's plenty of other postings for the same thing on Amazon, so don't order these. Bad quality control.

Perfect display for my Daft Punk helmet. Very easy to install, use and customize the images. I ran the display off of a small portable USB phone battery all night and it ran strong for a few days before I finally turned it off.

Ich habe mir eine Digitalaur (in Verbindung mit einen Raspberry) daraus gebaut. Das Tolle ist: weil es mir zu lang war habe ich es abgeschnitten und es funktioniert trotzdem einwandfrei. Ist zu empfehlen.

Fantastico

Der eigentliche Artikel gefällt mir gut und hat auch eine schöne leuchtkraft leicht anzuschliessen an einen Led Player oder Microcontroller . Jedoch denke ich durch die fexibilität des Planels falöen die Leds schnell aus. Ich habe von anfang an ein defektes Planel bekommen jedoch der Service ist super schnell und angenehm.

Not working.

Great matrix but it is crazy bright at full power and really does draw alot of power so for most uses make sure you drop brightness right down, at minimal brightness it can run from USB power, any more than minimum you'll need external power from a small external power supply or via molex or Sata power. An arduino atmega328p is more than enough to power any designs and I'm using a nano. To get the best look you'll want a diffuser of sorts in front of the led like frosted acrylic (the video uses a little wrapping tissue paper for the same effect)
