A single LED that can display multiple colors by adjusting RGB values, with each LED individually controllable by a controller.

In the text, two models were used: a circular one with 7 LEDs and a linear one with 8 LEDs.

The terminals total either 6 or 8, with the 6-terminal version comprising (IN, 2x VCC, 2x GND, OUT), and the 8-terminal version adding 2 more GNDs to the 6-terminal setup.

Connecting the OUT terminal of a NeoPixel to the IN terminal of the next allows for controlling multiple NeoPixels with just one pin on the board.
