Introduction 2812 shield adopts stackable design compatible with UNOR3 board It is an intelligent controlled LED light source that the control circuit and RGB chip are integrated into a 5050 SMD component Each pixel interior not only includes intelligent digital port data latch and signal reshaping amplification drive circuit but also includes a precision internal oscillator and a 12V programmable constant current control part effectively ensuring the highly consistency of the pixel point light color The data transfer protocol uses single RZ return to zero communication mode After the pixel power on to reset the DI port receives data from controller the first 24bit data is extracted by the first pixel and then sent to the data latch inside the pixel LED has the advantages of low driving voltage environmental friendly energy saving high brightness large scattering angle good consistency long life span etc Specifications of Single LED 1 Anti reverse protection circuit the reverse power connection will not damage the internal IC of the LED 2 IC control circuit and LED point light source use the same power supply 3 Control circuit and the RGB chip are integrated into a 5050 SMD component forming a complete control of pixel point 4 Built in signal reshaping circuit signals received will be wave reshaped first and then output to the next driver ensuring wave form distortion not accumulate 5 Built in power on reset circuit and power down reset circui
