A keyboard and mouse can be connected via the Raspberry Pi's two USB ports
The Pi requires a keyboard and mouse that use USB connections, so any modern device will do. The Raspberry Pi Model B, the only version currently on sale, has two USB ports on its right-hand side. These sit proud of the other, Ethernet (network) port. Attach the keyboard and mouse, checking that the USB connectors are the right way up before pushing them in.
Both the Pi’s full-size USB ports will now be occupied. This doesn’t matter in the short term but connecting additional USB devices later will require the purchase of a powered USB hub – the Logik L4THUB10 costs about £8.
