Up for sale are loose APA102/SK9822 RGB LEDs.  

This product will work with APA102/SK9822 protocol, and plenty of code is available for Arduino and other platforms. 

I personally use these products for RGB lighting experiments, and they are very fast and responsive with brilliant color.

Technical details

1. Product Overview :

SK9822 is a two-wire transmission channel three (RGB) driving intelligent control circuit and the light

emitting circuit in one of the LED light source control. Products containing a signal decoding module,

data buffer, a built-in constant current circuit and RC oscillator; CMOS, low voltage, low power

consumption; 256 level grayscale PWM adjustment and 32 brightness adjustment; use the double

output, Data and synchronization of the CLK signal, connected in series each wafer output action

synchronization.

2. Main Application Field:

● Full color LED string light, LED full color module, LED super hard and soft lights, LED guardrail tube,

LED appearance / scene lighting

● LED point light, LED pixel screen, LED shaped screen, a variety of electronic products, electrical

equipment etc..

3. Description:

● Top SMD internal integrated high quality external control line serial cascade constant current IC; 5V

application; default on electric lights;

● Control circuit and the RGB chip in SMD 5050 components, to form a complete control of pixel,

color mixing uniformity and consistency;

● The two-wire synchronous control.

●The three RGB output control, 8Bit (256) color; 5Bit (32) to adjust the brightness;

● The three constant current drive, self detection function specific signal

● The maximum frequency of 30MHZ serial data input

● The double data transmission, built-in support uninterrupted oscillation PWM output, can maintain a

static image.
