RGB LED stick - 8 x WS2812B

Do you like when everything shines like a Christmas tree on steroids? Then you’re in the right place! LED-1933 is a bar with 8 WS2812B LEDs, and compared to its sibling LED-1061, there’s one significant difference: the LEDs are packed more tightly. That means smoother color transitions and punchier lighting effects in a smaller space.

A bit denser, indeed, but is the proud High Density inscription on the back of the PCB justified? Well, judge for yourself; it’s clear that Mr. Chinaman has no qualms about bragging.

WS2812B LEDs come with built-in controllers and are easy to manage using Arduino or ESP8266 boards, with libraries like FastLED or Adafruit NeoPixel. They run on the standard 5V, and use a single data line for communication.

The dimensions remain compact, and the tight LED spacing makes this strip perfect for projects where space is limited, but you still want maximum lighting. Decorations, signs, case lighting – the only limit is your imagination (and maybe your microcontroller’s RAM). If you’re aiming to build full-on light walls, check out more WS LED products, including ready-made panels.

To use it in your project, you’ll need to solder a goldpin header or a cable. There are four pads, but only three connections are required – the outer GND pads are duplicates.

Power range is 4–7V (5V from an Arduino works perfectly), connect GND, and a control signal. You can chain multiple bars together and still use only one digital pin for control on your Arduino.

This LED bar works great with the Adafruit Neopixel library.

Specification:
