    É um bom produto, embora um dos LEDs esteja defeituoso, pois está sempre ligado (verde).

    Parece-me bem. A única coisa de que não gostei foi que havia um ponto de solda no meio da tira que interfere com a uniformidade. Vou colocar isto num alojamento para não haver problemas, mas se quiser que isto seja mostrado abertamente, pode ou não ser um desvio. Acabei de testá-lo com uma fonte de alimentação de 12 vDC e apenas os primeiros 5 LEDs piscam e a uma temperatura de 1 Hz. Atualizarei mais à medida que seguir em frente no meu projeto

    I cut the stripe and I checked all the connections. Here are some pictures to show how things are connected, in and out, etc.

    I have ordered 3 pcs of those 144 LEDs pr meter devices. I am quite impressed by the quality - first, it seemed that the line was not that flexible, but I later found out that this is not an issue at all. The light intensity of all LEDs is really equal. One can expect to make pretty good "video" devices with good quality - the overall image is uniform and good looking. Of course you will need a lot of "pixels" if you really want to make a big image screen. One little flow - the 144 pcs device is actually made by soldering 2 x 72 pcs together. The connection is not that good and the physical distance at the connection area is longer than the rest LED "pitch". This would need to be corrected if you need more seamless connection. It is visible on the image I provided below. It is really easy to program these LED lines - my 12 year old son learned to program them just for some minutes using Arduino board and the appropriate libraries. The color and the intensity (by PWM) can be programmed independently for each single LED using simple addressing algorithm. We have much fun with these devices!

    Arrived in 19 days. Very good condition but it was 4$ expensive than other sellers. Quality seams good, if you want to use the leds separate maybe it is difficult to manipulate soldering each one since the material does not have soldering points. There are two 72 led stripes connected = 144 leds. Will be checked later.

    The strip came pretty fast and was neatly packed on a reel. I ordered a black strip and it does not show any arrow for data direction, nor does it mention any DI or DO. How to determine the direction of the strip?

    just randomly inserted in a plastic back. of course not esd safe of course not in a proper roll so I hope the "pcb" was not damaged because of a kink...

    schöne und helle farben hatte schon welche wo der rot ton zu stark war und alle anderen farben überdekte

    It worked normally with LEDStrip on OMNIBUSF4-FC.

    Хорошие светодиоды 2812. Советую можно что то зделать.
