There are 20 full-color RGB LEDs on this stick. With only one signal pin you can control all 20 LEDs easily. The LEDs are WS2813 type that support signal break-point continuous transmission, which means you can continue to use other leds when one led is broken.
WS2813B IC, 3535 LED
Intelligent Reverse-connection protection.
The gray levels of each pixel are of 256, which achieves “256*256*256=16777216” full-color display.
The refresh frequency reaches to 2KHz.
Serial cascade interface, data receiving and decoding depend on just one signal line.
Dual-signal wires version, signal break-point continuous transmission.
