This driver has 4 of these currentcontrollers in parallel on both sides of the driver so 8X 350mA makes 2800mA max. The led MUST BE COOLED VERY 4... Read more

    Драйвер с хорошим током и несколькими режимами работы. Описание на сайте полностью соответствует полученному. Брал плату несколько меньшего диаметра, чем было нужно т.к. на сайте не нашел нужного размера. Для установки припаял по периметру платы проволоку (кольцо) тем самым увеличив диаметр до 4...

    Memory function works 70% of the time. For some reason memory doesn't work sometimes. Probably because I modded this board being too small I connected - of board to spring by wire and not perfect connection.
