USB (for “Universal Serial Bus”) is a standard for ports on your computer and cables with plugs that plug into them.

Why are we including USB in our glossary of electronics terms? USB not only transfers data between your computer and other devices, but it also supplies 5V of power and can be used to power things.

Arduinos, for example, use USB both for power and as your conduit for storing data on the device and getting data back out.

Our USB Adapter module uses a computer-connected USB cable to power your Circuit Scribe circuits.
