## Overview

The Rainbow Biscuit NS-LED-06 is a compact 3x3 WS2812B RGB LED matrix featuring a built-in logic level converter for seamless 3.3V to 5.5V MCU compatibility. Perfect for drone, quadcopter, and Arduino projects, it delivers ultra-bright 24-bit color output with full NeoPixel library support, enabling vibrant, chainable lighting effects in a lightweight 3.7g form factor.

## Description

Demo clips: https://www.youtube.com/watch?v=6rHHc1o5uec Dimensions: 26.67 x 26.67 x 3.3 mm, 3.7g  This is the easiest way possible to add small and ultra bright RGB LEDs to your project.  Each pixel of the three primary color can archive 256 brightness display, completed 16,777,216 color display.  Power the whole thing with 5VDC ( 3.5V ~ 5.5V works)  The pixels are arranged in a ZigZag layout, i.e. pixel(row,column): DI-(1,1)-(1,2)-(1,3)-(2,1)-(2,2)-(2,3)-(3,1)-(3,2)-(3,3)-DO. The LEDs are chainable by connecting the output of one matrix into the input of another.  These pixels have full 24-bit color ability by the built-in controller chip. Since the LED is so bright and compact, you need less current/power/space to get the effects you want.

## Features

- Upgraded NS-LED-06T with Logic Level Converter, 3x3 matrix type, ultra bright and colorful WS2812B digital RGB LED
- Easy and fun Drone/Quadcopter/Arduino project, Chainable design, Zigzag layout
- 256 brightness display and full 24-bit (16,777,216) color display
- Compatible with the Neopixel Arduino library
- 3.5V ~ 5.5V works, NS-LED-06T: Ok when a signal level is 3.3V from Naze32/Teensy (ARM Cortex MCUs), NS-LED-06: Need to use a high speed level converter (74AHCT245, etc.) or 3.7~4.2V power supply instead of 5V when a signal level is 3.3V from Naze32/Teensy
