CJMCU-2814 latest WS2812B-4 full-color RGB LED driver module development board four lights
Size: 15mm * 15mm
main feature
● intelligent reverse polarity protection, power supply reverse polarity will not damage the IC.
● IC control circuit with a LED light source utility power.
● control circuit and RGB chip in a 5050 package components constituting a complete external control pixels.
● built-in
signal shaping circuit, any one pixel signal is received through the
waveform shaping and then output to ensure line waveform distortion will
not accumulate.
● Built-in power-on reset and brown-out reset circuit.
● trichromatic color of each pixel can be realized 256 level brightness display, complete 16777216 colors all true color display , scanning frequency of not less than 400Hz / s .
● serial cascade interface, through a signal line finish receiving and decoding data.
● pass any two points in the transmission distance of not more than 5 meters without any additional circuitry.
● When the refresh rate of 30 frames / sec, the number of not less than 1024 points cascade.
● data transmission speeds of up to 8 00Kbps .
● light color highly consistent, cost-effective.
The main application areas
● LED full-color
light-emitting character string lights, LED full-color module, LED
full-color flexible light strip light bar, LED guardrail.
● LED spot light, LED pixel screen, LED shaped screen, a variety of electronic products, electrical equipment marquees.
product description
WS2813B is a set of control circuit and lighting circuit in one of the smart external control LED light source. Its appearance and a 5050LED lamp beads the same each element is a pixel. Pixels
contained within an intelligent digital interface data latch signal
shaping amplification drive circuit further includes a high-precision
internal oscillator and programmable 12V high-voltage constant current
control section, to ensure the effective pixel light color highly consistent .
NRZ data protocol uses a single line of communication, the pixels in POR, DIN terminal receiving the data transmitted from the controller, the first to send back 2 4bit data is
extracted after the first pixel, to the pixel internal data latch, the
remaining data processed through internal shaping circuit shaping
amplified by the DO output port begins forwarding to the next cascaded pixels, each pixel through a transmission, the signal reduction 2 4bit . Pixel
using automatic forwarding shaping technology, making the number of
pixels of the cascade unlimited signal transmission, signal transmission
speed is only limited.
LED has
a low voltage driving, high energy saving and environmental protection,
brightness, scattering angle, consistency, low power, long life and
other advantages. The control circuit is integrated in the LED above the circuit becomes more simple, small, easy to install even more.
