The LED board is designed to fit "in-line" from a USB-C lead to a typical WS2812 RGB LED strip or ring.
The software features a number of ways to work the LEDs, using settings and commands over MQTT.
USB sockets do not have to provide more than 500mA, but many do. Consider the current requirement for your LED strip and the power of your USB supply. However, you can probably run a strip of 100 LEDs of a typical USB charge plug.
