This key is perfect as very discreet, and feeds well into the USB port of the Raspberry Pi (low consumption). Beware though, this key has a power saving system. This is perfect for a desktop PC, but for a server used RPI has tendency to go into power save mode too easily, which has the effect of making the server unavailable. To avoid this, simply program a regular ping (eg your router), and disconnections are a bad memory. Shipped quickly in a nice package.
