This page will be expanded over time as new IC types become popular in Christmas lighting.
Always check the labels on your RGB pixels. V+/GND may be reversed, i.e. GND top and V+ bottom.
Connecting V+ from your power source incorrectly to your lights will likely damage them.
WS281xWS281x is 8-bit without a dedicated clock line. There are four common WS281x variants. The first two are:
WS2811 (separate IC), WS2812 (IC integrated in 5050 LED).
Pixel Pinout V+ DATA GND
A further two variants add an additional wire for data backup:
WS2818 (separate IC with data backup) and WS2813 (IC integrated in 5050 LED with data backup).

INK1003INK1003 is 8-bit and similar to WS281x (specifically WS2812). The 12V version typically will contain a built-in DC-DC 5V regulator every 50cm or 100cm, which means each 5050 RGB can be individually controlled even with a 12V power feed.
Pixel Pinout V+ (12v) V+ (5v) DATA GND

Caution! A 5V only version also exists without any DC-DC converters. Be sure to specify that you want the 12V version to your supplier if that is what you want.
