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

Works like a charm, easy to use. Simple to code.

I originally was suspicious of the rather low price, but all 256 Pixels are addressable and working properly. I'm not seeing a noticeable voltage drop across the array when they turned up to full white. Driving the full array with an external 5v supply while driving the data pin at 3.3v from a Raspberry Pi Pico board. I've used this display very sparingly for 2-3 years with no complaints.

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.

These worked great! Ordered these for a 3D project and will order again.

If you buy this flexible LCD panel you will find that all LEDs are connected in series from left upper corner to the right bottom corner. If you gold the display, the input wires - I removed all the other wires - and they are behind the left bottom corner, your LED #0 is on left upper corner. I made a demo program using Seeeduino (or one can use the Arduino Nano....) and it is on the Github. Amazon doesn't like when I put here the shortcuts to it's web address, sorry.

Great LED panel, good brightness and color options and feels well made and durable. This is a good size for basic LED projects. I used it with an Arduino; keep in mind you will need an external power source for it as well.

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.

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.

Llego bien empaquetado con su adaptador.

Great colors, quite bright. Good contrast. Honestly, all positive. Used with an arduino mega using FastLED.

A very nice RGB panel. The ordering of the LEDs is a little non-intuitive, but easy to figure out. I particularly like how easily it curls into a cylinder. Nice that there are additional places to inject power.
