APA102 is a intelligent control LED light source that the control circuit and RGB chip are integrated in a package of 5050 components. It internal include 3 groups shift register sand Self-detection signal decoder circuit.Also include a 4.5V voltage regulator part and continuous oscillator effectively ensuring the pixel point light color height consistent.
The data transfer protocol use two line decoder mode. After the pixel power-on reset, the DIN port receivedata from controller after decorder , the first pixel collect initial 24bit data then sent to the internal data register, the other data which reshaping by the internal signal decorder circuit sent to the next cascade pixel through the DO CO port. After transmission for each pixel.LED with low driving voltage, environmental protection and energy saving, high brightness, scattering angle is large, good consistency, low power, long life and other advantages. The control chip integrated in LED above becoming more simple circuit, small volume, convenient installation.
