This LED board is essentially a USB stick with a light instead of memory. You can put it in any USB port and the light will work.
However it can be easily converted to be used in projects by soldering a USB cable to the outside contacts to create a small but functional light that can be use in a variety of projects. It operates via an open-end USB cable that can be powered by any USB socket including Mobile phone chargers, USB output from a PC or Laptop and even portable chargers with a USB output.
