excellent quality. caution: those newer series wont work with logic high of 3,3 volts.

Awesome product, i've ordered 2x100, all works i've uses fastled library and managed to make a 20x10 matrix to display some leds without problems

Whell, I ordered the black boards with the black led case on it (as on the picture), but I got the third variant. Black board with white cases on it. Someone maybe colorblind? I ordered 12 plates and they all came unharmed. Not yet tested the leds but expect that there will be no issues. For a jumbo display with 1200 of these pixels you still have a scan frequency of 27,8Hz (carrier frequency = 800kHz). For higher scanrates or bigger screens with acceptable scan rates, just divide into sections and adapt the control software. For testing the chips you can provide supply voltage to V+ and V- and an oscillator signal with a frequency of 800kHz and a dutycycle of 0.68 between the Din and V- line.

Parece-me bem, um deles foi testado.

Seems good, one of them tested.

Chegou rápido e chegou sem problemas, muito boa qualidade da miniplaca com chip WS2812B. Eu recomendo fortemente porque ele tem uma grande qualidade e pode ser usado em muitos projetos arduino e drones, por exemplo.

Arrived fast and arrived without problems, very good quality of the mini board with WS2812B chip. I strongly recommend it because it has a great quality and it can be used in many arduino projects and drones for example.
