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.

WS281x
WS281x 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).
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).
WS2811 (separate IC), WS2812 (IC integrated in 5050 LED).

INK1003
INK1003 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.
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.

GS820x
GS820x is 8-bit without a dedicated clock line. An additional fourth wire is used as a backup data source. It has an effective colour depth of 12-bit through gamma correction and has an automatic test mode. There are two variants:
GS8206 (separate IC with data backup), GS8208 (IC integrated in 5050 LED with data backup).
GS8206 (separate IC with data backup), GS8208 (IC integrated in 5050 LED with data backup).
While this IC is compatible with WS281x configured controllers, mixing GS820x/WS281x pixels off the same output may cause issues in certain environments. J1SYS controllers should have their outputs configured with speeds around 3200-3600.
