WS2812B-4-bit RGB LED full-color driver 4-bit color lamp module development board

Size: 15mm*15mm

Main feature

● Intelligent anti -connection protection, the power supply reverse will not damage IC.

● IC control circuit and LED point light source publicly use a power supply.

● Control circuit and RGB chip integrated in a 5050 packaging component to form a complete external control pixel.

● Built -in signal plastic surgery circuit, any pixel point receives the signal and then outputs through waveform plastic surgery to ensure that the line waveform distortion of the line will not be accumulated.

● Built -in -on -power reset and power -off reset circuit.

● Each pixel color color color color can be displayed at 256 brightness display. Completion of the full real color display of 16777216 colors, the scanning frequency is not less than 400Hz/s.

● Serial -level connector, you can complete the data receiving and decoding by a signal line.

● Any two point transmission distance does not need to increase any circuit when no more than 5 meters.

● When the refresh rate is 30 frames/second, the number of sectors is not less than 1024 points.

● Data sending speed can reach 800kbps.

Product overview

WS2813B is an intelligent external control LED light source integrating control circuit and luminous circuit.Its appearance is the same as a 5050LED lamp bead, and each component is a pixel.The internal pixel contains the intelligent digital interface data lock -to -signal plastic surgery driving circuit, and it also contains high -precision internal oscillator and 12V high -voltage programmable fixed current control part, which effectively ensures that the color of the pixel light is consistent.

The data protocol adopts a single -line zero -code communication method. After the pixels are powered on and reset, the DIN terminal accepts data transmitted from the controller. The first 24bit data that is sent by the first pixel is extracted.The data locks, the remaining data will be reposted and output to the next -level pixel dot through the DO port through the DO port, and the signal is reduced by 24bit each passing through a pixel point transmission.The pixel point adopts automatic plastic transmission technology, so that the number of levels of the pixel point is not limited by signal transmission, and only the limited signal transmission speed requirement.

LED has the advantages of low -voltage driver, environmental protection and energy saving, high brightness, large scattered angle, good consistency, ultra -low power, ultra -long life and other advantages.Integrate the control circuit on LED, the circuit becomes simpler, the volume is small, and the installation is easier.
