excellent quality. caution: those newer series wont work with logic high of 3,3 volts.
un surtido amplio de leds, me gusto el enpaque uno recorta los que necesita
Buen producto conforme a lo descrito
molto buono e illuminare molto bene niente ma costa abbastanza saldarlo
wow...... very fast delivery . thanks bangood but little costly
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.
Super qualità! Ben confezionato, imballaggio antistatico e protettivo, consiglio vivamente!
Sembra buono, uno di loro ha fatto il test.
Arrivata velocemente e arrivata senza problemi, ottima la qualità del mini board con chip WS2812B. Lo consiglio vivamente perché ha una grande qualità e può essere utilizzato in molti progetti di arduino e droni per esempio.
