    Подключил его к DIYMore Pro Mini Strong (Arduino Pro мини-клон), модифицировал пример Адафрута NeoMatrix пример эскиза и все работает хорошо. Очень яркий при полном освещении. Теперь ждем новых панелей, чтобы сделать мозаичный дисплей...

    Very very bright leds on a nice soldered board. I had troubles getting it to work with the examples from ADAFRUIT. Turned out that the pin labled 'DIN' on the board is NOT the data input !!!. After changing it to the 'DOUT' pin everything worked fine. Maybe this would be a nice addition to the product description.

    Come descritto altrove i pin sono al contrario ma il prodotto funziona perfettamente li ho presi per fare una lampada da tavolo con colori e luminosità variabile controllata da telefono ma sono rimasto stupito dalla quantità di luce che generano , li ho dovuti regolare al minimo xche al massimo arrivano ad assorbire 1ah a pannello a 5v e la luce è troppa

    I purchased the "CJMCU 64 Bit WS2812 5050 RGB LED Driver Development Board" from Banggood.com on March 2, 2017. I was very disappointed at first that I could not get this LED matrix to function, no matter how I wired it to my Arduino Uno (or Nano) and no matter what sketch I wrote or used. Nothing I did could get it to work. Testing the individual WS2812 LEDs showed no problems, but I did notice that the front of the CJMCU-8*8 board had printed labeling showing "WS2812B-64 RGB LEDS". This was clearly incorrect as it was obvious from just looking at the individual 6 pin LEDs that they were in fact WS2812's, which they were supposed to be, so the "WS2812B" label was a printing error. This made me suspicious of the quality assurance (or lack thereof) of the manufacturer of this product. When I continued my visual inspection of this board by turning it over, I discovered a very disturbing issue with the board and the cause of my inability to get it to function properly. The back of the board was also incorrectly printed. The entire printed surface of the board was printed upside down. This caused the individual markings on the back of the board to be reversed. Not much of a problem for the name "CJMCU-8*8", but a big problem for the 6 pin labels. Since the board was printed upside down, the pin labels were reversed and the DIN pin was incorrectly marked as "DOUT" and vice-versa for the DOUT pin, which was erroneously labeled as "DIN". This caused me to hook up the board incorrectly, trying to power and control the WS2812 LED's from the wrong side. No mystery that it never lit up that way. As soon as I connected my inputs to the pins that were mistakenly marked as "outputs" it worked just fine. Since then the board has worked well, so I am just disappointed that I wasted so much time trying to figure this problem out. It seems that other people have had the same problem with this matrix board and it continues to be shipped this way, so I probably should've checked the comments on the BG web site before I wasted my time troubleshooting it. I hope future purchasers of this item will read this, examine the board they receive and save themselves from similar frustration. I have included two photos that graphically demonstrates the problem cause by this printing error.

    Большое значение в продаже желание вы могли бы получить их в групповой покупки или оптовой покупки только заказ 9 будет заказывать еще 12 платы для других проектов

    Доставка на несколько дней раньше, чем ожидалось, товар упакован в антистатический пластиковый пакет. Хорошо работает со смежными библиотеками, яркими цветами. Могу порекомендовать!

    Отличная панель. Заработаю его через несколько минут с неопиксельной библиотекой. Очень умный.
