The board has Built-in the four Color LED (WS2812B) with intelligent controller (See
and the four LED are connected in series controlled by one GPIO line. The WS2812B is an
intelligent control LED light source that the control circuit and RGB chip are integrated in a
package of 5050 components. It internal includes intelligent digital port data latch and signal
reshaping amplification drive circuit. Also includes a precision internal oscillator and a 12V voltage
programmable constant current control part, effectively ensuring the pixel point light color height
consistent.
