General description

APA104 is a intelligent control LED light source that the control circuit and RGBchipareintegrated in a package of 5050 components. It internal include intelligent digital port datalatchand signal reshaping amplification drive circuit. Also include a precision internal oscillator anda12V voltage programmable constant curre-nt control part, effectively ensuring the pixel point lightcolor height consistent. The data transfer protocol use single NZR communication mode. After the pixel power-onreset, the DIN port receive data from controller, the first pixel collect initial 24bit data thensentto the internal data latch, the other data which reshaping by the internal signal reshapingamplification circuit sent to the next cascade pixel through the DO port. After transmissionforeachpixel，the signal to reduce 24bit. pixel adopt auto resha-ping transmit technology, makingthepixel cascade number is not limited the signal transmission, only depend on the speed of signal transmission.

LED with low driving voltage, environmental protection and energy saving, highbrightness,scattering angle is large, good consistency, low power, long life and other advantages. Thecontrol chip integrated in LED above becoming more simple circuit, small volume, convenient installation.
