| Beautiful, full-color LED pixel strings with pre-soldered JST style connectors. Not only are these fully waterproofed, but each LED is also independently addressable, opening up entirely new lighting possibilities. Each LED is powered by an WS2801 IC. Each end of the pixel string has a JST-style connector. Data in and clock in can be found on the female connector; data out and clock out on the male connector. Pinout is as follows:
The WS2801 employs a 2-wire serial data connection, similar to SPI or I2C. ICs are chained together which means whole strings can be controlled using just 2 pins on your microcontroller. Data is clocked in starting with the MSB of the red gray scale data and ending with the LSB of the blue gray scale data. See picture below for details. There is plenty more information available in the datasheet linked to above.  (Click to enlarge) |
