Keyestudio 40 RGB LED 2812 Pixel Matrix Shield for Arduino
Keyestudio 2812 shield adopts stackable design compatible with UNO board. It is an intelligent control LED light source that the control circuit and RGB chip are integrated in a 5050 SMD component. It includes intelligent digital port data latch and signal reshaping amplification drive circuit. 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 NZR communication mode. After the pixel power-on reset£¬ the DI port receives data from controller£¬ the first pixel collect initial 24bit data then sent to the internal data latch. LED with advantages of low driving voltage£¬ environmental-friendly£¬ energy saving high brightness£¬ large scattering angle£¬ good consistency£¬ long life span etc.
