• Integrated control chips in each LED enable over 16 million colors per pixel

Product Description

This RGB LED board features multiple addressable WS2812 light-emitting diodes arranged in a row and wired at the factory. In addition to the three colored LEDs, each LED contains an integrated control chip that stores the color value and brightness for that individual LED. This allows each LED to light up independently with its own color and brightness.

Control is carried out via a single digital data line. A microcontroller sends the color information for all LEDs as a serial data stream. Each LED extracts its own color data and forwards the remaining data to the next LED. This allows any number of LEDs to be controlled using a single signal line. Since the data line operates sequentially, separate lines for each LED are unnecessary, saving microcontroller pins.

The supply voltage is between 3.3 and 5 V. Operation requires a microcontroller with a digital output and a suitable control library such as Adafruit NeoPixel or FastLED. The board is suitable for running lights, color gradients, and status indicators. One specific example is animated progress bars in test equipment, where each LED indicates a different operating phase while smoothly changing color and brightness.

Since the LEDs are already soldered and equipped with jumper pins or solder pads, there is no need to solder each one individually. Additional WS2812 modules or LED strips can be connected in series via the output and controlled together. The board is available in several sizes with different numbers of LEDs.

Safety Notice

Observe the polarity of the power supply and data line when connecting the module. This module is intended exclusively for building prototypes and for testing and development purposes; it is not intended for installation in household electrical circuits. If you have questions about the power supply or connection to other systems, consult a qualified electrician.
