WS2812B 5×5 RGB LED Module

The WS2812B  5x 5 RGB LED Module has a built-in Full-Color Driving Lights Circular Development Board and a round black shape. 25 super bright smart NeoPixels LED arranged in a 68mm outside diameter circular PCB.
These ring RGB lamps can be simply connected via the output pin cascade one to the other’s input pin (DI-DO).

In this way, by using only one single chip you will be able to control as many LED lights as possible, each LED lamp is integrated with a driver chip in it so that our LED becomes intelligent and addressable.
Each has a -18mA constant current drive, so the LED color will be very uniform, even if the voltage change is the same, do not need an external resistor current limiting resistor to make the overall design of the RGB lamp ring slim, as you see so simple and easy to use. With a 5V power supply to drive the RGB lamp ring.

Single wire communication, to maximize the reduction of I/O port pressure, and the use of the RGB WS2812B driver chip, so that the peripheral circuit requires only a single capacitor can meet the needs of the circuit, give people the enjoyment of beauty, in addition, this RGB ring, but also through a simple D-out input port, and the other using the same chip RGB lamp cascade, without need considering the shape of the limit.

Specifications

• Intelligent reverse connection protection, reverse power connection will not damage the IC.
• The IC control circuit shares a power supply with the LED point source.
• The control circuit and RGB chip are integrated into a 5050 package component to form a complete external control pixel.
• Built-in signal shaping circuit, after any pixel receives the signal, it is waveform-shaped and then output to ensure that the line waveform distortion will not be accumulated.
• Built-in power-on reset and power-down reset circuit.
• The three primary colors of each pixel can realize 256 levels of brightness display, complete the true color display of 16777216 colors, and the scanning frequency is not less than 400Hz/s.
• Serial cascade interface, which can receive and decode data through one signal line.
• There is no need to add any circuit when the transmission distance of any two points is less than 5 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.
• The color of light is highly consistent and cost-effective
• Board Dimension (LxWxH MM): 40x40x3mm
• Weight: 4g.
