1.Control IC SK6812/ws2812b  inserted in 5050 RGB LED diode , supporting numerous color-change effects .black PCB optional . 2.It comes in one piece separated by a 3Pin JST SM connector and extra Power /Ground Wires . 3.Flexible PCB material . This matrix has a thick flexible PCB backing that can be gently bent and curved around surfaces 4.This matrix with 256 leds, you could use over 15A of current if you turn on all the LEDs on to white (which we really do not recommend because we don’t think the flex PCB can handle that much current in a long time ). Try to keep the current draw at under 5A. 5.These are awesome 8×8 individually addressable RGB matrix panels. Composed of 8 columns x 8 rows of WS2812B (WS2812/WS211 protocol) individually addressable LEDs on a flexible PCB, these panels have 64 LEDs and they can be daisy-chained to make bigger signs or panels! You can create animations, games, or even incorporate them into a fun e-textiles project. On top of all that, thanks to its flexible backing, this LED Matrix can be bent and bowed to fit onto almost any curvy surface. 6.These panels require a 5V low voltage input for power which needs to be able to source a good amount of current – up to 3.8A in most uses (3.8A if all LEDs are set to bright white, which is NOT recommended). Attached to each flexible LED matrix are two 3-pin JST SM connectors and two sets of bare power cables (input / output), which provide you connections for DC5V+, COM-, DAT, and GND. 7.Pls note that WS2812B are a bit different than the standard WS2801 ICs, these do not use separate clock and data lines.
