WS2812E-V5/W

WS2812E-V5/W Intelligent External Control Integrated LED Light Source

Main Features
● The IC control circuit and the LED point light source share a power supply.
● The control circuit and the RGB chip are integrated in a 5050 package component to form a complete external control pixel.
● Built-in signal shaping circuit. After any pixel receives the signal, it undergoes waveform shaping and then outputs it to ensure that the line waveform distortion will not accumulate.
● Built-in power-on reset and power-off reset circuits.
● The three primary colors of each pixel can achieve 256 levels of brightness display and complete the full-color display of 16777216 colors.
● The port scanning frequency is 2KHz/s.
● The serial cascade interface can complete the reception and decoding of data through a signal line.
● No circuit needs to be added when the transmission distance between any two points does not exceed 2 meters.
● When the refresh rate is 30 frames/second, the number of cascades is not less than 1024 points.
● The data transmission speed can reach 800Kbps.
● Highly consistent light color, high cost performance.

Main application areas
● LED full-color luminous character light string, LED full-color soft light bar hard light bar, LED guardrail tube.
● LED point light source, LED pixel screen, LED special-shaped screen, various electronic products, electrical equipment marquee.

Product Overview
WS2812E-V5/W is an intelligent external control LED light source that integrates control circuit and light-emitting circuit. Its appearance is the same as a 5050LED lamp bead, and each component is a pixel. The pixel contains an intelligent digital interface data latch signal shaping and amplification drive circuit, a high-precision internal oscillator and a programmable constant current control part, which effectively ensures the high consistency of the color of the pixel light.

The data protocol uses a single-line return-to-zero code communication method. After the pixel is powered on and reset, the DIN end receives the data transmitted from the controller. First, the 24-bit data sent is extracted by the first pixel and sent to the data latch inside the pixel. The remaining data is shaped and amplified by the internal shaping processing circuit and then forwarded to the next cascaded pixel through the DO port. After each pixel is transmitted, the signal is reduced by 24 bits. The pixel adopts automatic shaping forwarding technology, so that the number of cascades of the pixel is not limited by signal transmission, but only by the signal transmission speed requirement. The port scanning frequency of up to 2KHz will not flicker under the capture of high-definition cameras, which is very suitable for the use of high-speed mobile products. The RESET time of more than 280μs will not cause false reset even if an interrupt occurs, and it can support lower frequency and cheaper MCUs. LED has the advantages of low voltage drive, environmental protection and energy saving, high brightness, large scattering angle, good consistency, ultra-low power and ultra-long life. Integrating the control circuit on the LED makes the circuit simpler, small in size and easier to install.
