WS2812B RGB 5050 SMD Flexible Modules 8x8 16x16 8x32 Pixel Panel Matrix Screen WS2812 IC Led Module Individually Addressable DC5V

1.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). 2.Using voltage 5V DC. higher than 5V DC will destroy it. 3.Do not bend strip sharply. Using a programmable controller and you can program every led just you like. Every one led has its own IC chip.one IC controll one led.The chip buil in led. Flexible PCBs are not designed for repeated flexing! 4.If you need better led strip performance, you can use a K-1000C controller or another programmable controller.
