These are addressable RGB LED strips that come packed with 15 LEDs(0.5M) or 30 LEDs(1M) . Except the features of high brightness and full color, you can control each LED RGB individually, and each of these strips are enclosed by a flexible silicon jacket  to protect your LEDs . It is fashionable for you to create cool lighting effects for your home decorative, fish tank, your car or perhaps cabinet lighting in your kitchen.
With a 3-pin connector, you can use Me RJ25 Adapter to connect the strip to Makeblock Me Orion Board like below picture. Otherwise we have provided Arduino library for easy programming. 
Note: Makeblock Me Orion Board can provide up to 3A/5V for power out to drive a long RGB LED strip(about 240 LEDs).
Features:
 High brightness and full color RGB LED
Be able to control each LED RGB individually by programming
15 WS2812  LEDs(0.5 meter)
Comes with Arduino library for easy programing
 
Specification:
Working voltage:          DC 5V
 Working currrent:       1.8A/meter
 Working temperature:  -40???60??
Viewing angle:             ??140
 Lifespan:          MTBF??50000h
 Size:500 x 13 x 3 mm(Length x Width x Height) length of power cable are not included
    Note: the working current (1.8A/meter) is the peak current when the strip lights up  three colors with maximum brightness. When you light up less than three colors or lower the brightness, the current will reduce more
