30mm Dots - 12V Digital RGB LED Pixels (Strand of 20)

Strand of 20 weatherproof 30mm pixel clusters, each containing 3 RGB LEDs and an 8-bit PWM controller (24-bit color) in a translucent white enclosure. Powered at 12V via a 4-conductor cable (+12V, GND, data, clock); daisy-chained and clocked by a microcontroller such as Arduino.

+12VDC
Positive 12 V supply conductor for the WS2801 pixel strand; Adafruit states the 4-conductor cable has +12VDC, ground, data and clock.
Type · PowerVoltage · 12V DC
GND
Ground conductor in the 4-conductor pixel cable; power wires are brought out separately for wiring to a DC supply.
Type · GroundVoltage · 0V
DATA
Serial data input/control conductor; Adafruit states data is shifted down from one pixel to the next and can be driven from a microcontroller digital pin.
Type · Signal
CLOCK
Clock input/control conductor for the WS2801 pixels; Adafruit states the pixels are clocked by a microcontroller and the cable includes data and clock.
