8x32 LED Matrix 256 Pixels WS2812B Digital Flexible LED Panel Individually Addressable Full Dream Color DC5V

I got two of these and connected them to a controller and a regular USB power bank. I had to get the cable and the power bank separately. I used double sided sticky tape and attached them to the milk crate that I attached to my bike's rear rack. It looks awesome at night and worked flawlessly at Burning Man. I was super stoked!

My Vpin cab houses a 50" 4K TV so my cab is wider than normal. I was able to put 2 of these together to make 1 large matrix. It was easy to do since these have plugs on each end. I wasn't going to add addressable leds to my cab but now I am sure glad I did. If you are on the fence deciding to add one of these to your cab or not, just do it. You will not regret it. Great product, worked right out of the box and the leds are super bright even with tint over them.

I picked this up to use in a 3D printed Zootopia crosswalk indicator (you know the one) from Thingiverse. The original design called for pushing individual LEDs through holes, but I modified it to use clear PLA and backlight the whole thing instead. This panel was a perfect fit.I’m running it with an Arduino and a 5V 4A power supply. It cycles between three states: green for “walk,” flashing red for countdown, and solid red for “don’t walk.” The colors are bright and responsive, and the animations run smooth. The matrix uses a 3-pin JST connector, but it was easy to adapt with a JST-to-Dupont cable to hook into the Arduino’s header pins. You can also just use jumper wires directly if you don't mind a little DIY.

No issues. Worked as advertised. Looks good.

Not too much too much to say here. It works well and the board is nicely flexible. I needed to make a cylindrical display, and it worked great for this. One minor downside - not much documentation on how the thing is wired. But this is trivial to discover by lighting the LEDs in turn. I had a bit of trouble getting color consistency at different brightness levels, but this can probably be fixed with a better color correction model.

Bright panel - as expected.

The media could not be loaded. Works great with Arduino and other LED drivers, we merged three panels together into one 16 x 48 LEDs, using a 5vc DC 5 amp power supply. We use a Microphone and then graph the sound waves coming in through the MIC. The display looks awesome and works as designed. I also added a brightness control into the project and a Save settings button using the internal EEProm on the MCU 2560. The hardest part was converting my code from horizontal LED manufacture to vertical LED manufacture. The coding is a little different to create a 2 dimensional Cartesian plane with LED (x, y) where x in [1..48] and y is in the set of [1..16]. It's cool to be able to address each LED individually.

The WS2812B is a pretty common addressable LED. There is not much variation in how vendors put these LEDs on flexible printed wiring substrates (generally, the number of LEDs per meter and their water resistance are the main differentiators). I needed a 16 x 16 display for a color light organ, and this display was exactly what I needed at a very good price. I also recommend using an ESP-32 with WLED software to drive the display. Very easy to implement.
