Dynamic led stripat high brightnesswith 60 pixels per meter, latest generation WS2815 integrated chip with backup function that avoids signal interruption in case of pixel breakage. For indoor use (IP20 degree of protection), black PCB. Dual signal version (back-up), continuous transmission from the point of signal break. If one led is damaged, it will not affect the operation of the other leds. With 4-pin male connector and separate power/ground wire at both ends for easy interconnection and power connection. Individually Addressable: Each LED has 1 IC, each LED can be individually addressed and show any color you want. The strip can be cut between each LED without damaging the strip.WS2815 digital LED stripdynamic integrates all electronic components into a single 5050 fixture, without the need for other peripheral electronic components to help form a complete internal control pixel. Meanwhile, WS2815 LED strip reduces the resistance caused by product inversion during installation. The refresh rate refreshes at 2 KHz. It supports the lowest frequency and cost-effective MCU. The data transfer protocol uses a single NZR mode of communication. Each pixel adopts automatic reshaping transmission technology, making the numbers of pixel cascade not limited to signal transmission, but only related to signal transmission rate. The BIN receives the data signal, which ensures that any damage of the IC will not affect the signal cascade transmission, and make the BIN in the signal receiving state until restart after power off.
