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
Πολύ καλά και πολύ καλά. Τίποτα, αλλά κοστίζει αρκετά για να το συγκολλήσεις
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.
Πολύ καλά συσκευασμένη, αντιστατική και προστατευτική συσκευασία, σας συνιστώ ανεπιφύλακτα!
Seems good, one of them tested.
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.
