Digital RGB Addressable LED Weatherproof Strip 144 LED (SK9822) – 1m (Adafruit DotStar compatible)

DESCRIPTION

This flexible RGB LED strip uses the APA102 LED chips instead of the older WS2801 chips, LED strips that use these chips are often referred to by the name DotStar. This is a library created by Adafruit designed for use with this type of LED driver chip. The APA102 chips are easier to control and offer faster PWM rates for flicker free performance.

There are 144 addressable RGB LEDs per meter on a white PCB, and each strip is sold in a 1 metre long length. Each strip can be easily cut or can be ‘daisy chained’ with other strips in order to produce long chains of LEDs.

Each LED on the strip is 5050 size, and has an embedded microcontroller inside it which controls brightness levels, and interprets the data you send it. Each strip needs two wires to control all LEDs, one clock and one data. This arrangement makes it easier to use with slower devices like the Arduino Uno. At the ends of the strips are male/female 4-pin JST-SM plugs which allow multiple strips to be connected. The power lines are broken out onto separate wires for easy

The power supply to the strip is 5V. It’s wise to consider that each LED can consume around 60mA at full brightness – multiply that by 144 (per metre) and you have over 8.6A. We recommend a relatively meaty power supply, with connections every 2 to 3 metres on a long run strip.

Please note: 

• The exact LED chip used in these strips can vary from batch to batch between the SK9288 and the APA102.
