BTF-LIGHTING WS2812B RGB IC Pure Gold 5050SMD Individually Addressable 16X16 256 Pixels LED Matrix DC5V Flexible FPCB Full Color Image Video Text Display Light IP30(No Adapter or Controller)

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 serviceNice matrix displayWould buy again

This is a good panel at a good price. I ordered two at $37.88 each, and tested them first thing to make sure there were no dead pixels. Both panels work flawlessly. Color rendering is good, and is consistent across the panel. Each panel was in a nice white box, but I was surprised that instead of being placed in an ESD protective anti-stat bag, the panels were wrapped in bubble wrap, known for holding static charge. My only issue is that the advertised size is incorrect - they are not 0.48ft by 0.48ft. They measure 6 5/16 inches (square), which is 0.53ft. Your enclosure needs to be at least 6 3/8' inside measurement. If I had built my enclosures relying on the 0.48ft description I would've been rather angry because the panels will not fit inside a 6" square hole. WS2812 LEDs get a little warm when holding a bright color over time and this panel does as well, since the LEDs are closely spaced. You need to give them good ventilation.For those reviewers whining about the serpentine addressing - this is the most efficient way to connect the rows (or columns). Build your own panel and you'll see. There is a simple solution - simply create a 2D ([rows][cols]) map that converts a logical row+column position into the corresponding physical position in the panel.

The media could not be loaded. 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 blackNow 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

This is a 5 star display but I subtracted one star to the lack of documentation.This display has rich colors and works well with the FastLED library. The package arrived per the suppliers commitment and was well packed. I did see some flicker but at this time I'm attributing it to my power supply. I'm getting a 1000 uf lytic to reduce the demand on the supply. I found out that the flickering was due to my driver. I switched to an Arduino UNO and everything worked great. I'm impressed with the brightness. I dimmed it down and it still supplied plenty of light. A quick connector was supplied which made it easy to interface it to the supply and the data source.Opportunities are as follows. I didn't receive any documentation and when I went to the site the product wasn't listed. I'm still confused on why there are two wires in the center of the matrix labeled 5v and DIN. I can see having the power coming in at the center but why the data also. I assume there was a reason but without any information I didn't use it.

I like these lights. Just wish they weren’t so expensive

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.

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

The media could not be loaded. This display is awesome and works great with Arduino uno and Atmega 2560. I used pin 8 on Atmega328p and pin 53 on the 2560, both work. I converted the linear addressing into a 2 dimensional plane for addressing each led individually. Works great!
