Digital RGB LED Weatherproof Strip (White PCB; 30 LED/1m)

 

 

Description

The strips are sold in 1/4/5 meters increments with the maximum length of a single,continous strip being 5m.Silicone end caps and 2 or 3-pin JST SM connector male/female pair are included with each strip!

 

These flexi-strips are without a doubt the mosr convenient,cost-effective option for using the WS2812 RGB LEDs in any lighting project.The tiny 5mmx5mm(also known as 5050) RGB LEDs are mounted on a flexible,white,slim PCB that can be cut to any length:from a 1-LED 10mmx33mm piece,up to a 10mmx5m continuous piece.You are not limited to 5m,2(or more)separate strip can be interconnected using the included 3-pin JST connector male/female pair.The maximum length of the strip is only determined by the number of LEDs you controller can handle(more info below).Each WS2812 on the strip includes 3 super bright LEDs(red,green,blue)and an embedded drive circuit(WS2811) that only requires one data input to control the brightness and color of the 3 LEDs.

 

Weatherproof packaging

The flexible PCB and WS2812 RGB LEDs are packages inside a 12.5mm-wide,translucent,silicone sleeve that has an IP65 waterproof rating.Given that we want to offer you the option of cutting the strips to any desire length,we also sell additional end caps separately,which allow the strips to be sealed up again after cutting.

 

Features

1.       Sold in 1/4/5 meter increments,with 5 meters being the max length of a single,continuous strip

2.       Multiple strips can be interconnected using the included 3-pin JST connector male/female pair or by soldering their respective ends together

3.       30 individually addressable RGB LEDs(WS2812) per meter

4.       IP65 waterproof rated,translucent,flexible silicone package

5.       Additional wiring included(power and ground) for easily connecting and external power supply

6.       Flexible PCB and silicone sleeve can be cut into pieces as small as 10mmx33mm

7.       Internal signal reshaping amplification circuit(inside embedded WS2811)

 

Requirements

Power

In order to drive 30RGB LEDs(for a 1 meter strip)at maximum brightness,the power supply need a source 1.75-1.8A@5V(9Watts). As mosr modern computer ports have very robust current-limiting circuitry,you can run a strip from a microcontroller board like the Arduino Uno R3 that is powered from a computer’s USB port.However,after putting matters into erspective-a single WS2812 package contains 3 LEDs(R,G and B)that require 20mA each to operate properly(Forward current specification),the 20mAx3x30=1.8A requirement is a lot higher than what a standard USB port can source:500mA max-we strongly recommenc using and external power supply.

 

Communication speed

The WS2812 package includes a Data In and Data Out pin that allows them to be connected sequentially.This means that we truly need nothing but one data line to control several of them(in additional to Power and Ground).However,at the expense of needing only one data line for control,there comes a demand for highly precise timing in the signal that we provide.For this reason,a real-time microcontroller(e.g.ARV,Arduino,PIC)is required.With some twesking of the stock firmware,it is possible to even use a Linux-based microcomputer or an interpreted microcontroller such as the Netduino or Basix Stamp.

 

Memory

Because the LEDs are connected serially,we need to specify the display data for each and everyone of them.The display data need to reside in the controller’s RAM so that they can be read and written with timing(speed) precison that is need.Most Arduino Uno R3 programs leave about 400B of RAM unused,and each WS2812 needs 24 bits of data(8 bits for each R,G and B value).This implies that up to 135 WS2812 LEDs could be driven by an Arduino Uno.R3.Other microcontroller boards such as Arduino Mega have more RAM,and consequently can drive more LEDs.

 

Strip length and connectors

The strips are sold in 1m increments with the max length of a single,continuous strip being 5m.Silicone end caps and 3pin JST connector male/female pair are included with each strip!

Each flexible PCB has “-spaced,3pin pads at both ends that can be soldered onto if a strip is cut.In addition,two strips can be interconnected using the included 3-pin JST connector male/female pair.
