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

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.

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.

No issues. Worked as advertised. Looks good.

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.

The media could not be loaded. I 3D Printed a enclosure for this panel and it's worked great. ESP32S running WLed with a 12v 3A power supply.

"Adafruit_NeoMatrix matrix = Adafruit_NeoMatrix(32, 8, PIN, NEO_MATRIX_TOP + NEO_MATRIX_LEFT + NEO_MATRIX_COLUMNS + NEO_MATRIX_ZIGZAG, NEO_GRB+ NEO_KHZ800);" worked to set it up for a simple text display.

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.

The wires are stranded with just a few thinner than hair strands. I cannot strip them without breaking strands and they're so thin, they do not stay twisted. They are soldered on facing the wring direction if you want to connect with others The panel can draw 15 amps but the wires are no where near rated for that much current flow. I thought other brands got the wire as thin as possible but this one is thinner yet!
