Both the keyboard and mouse follow the design aesthetic used by the Raspberry Pi Foundation for their official case, always a featured staple of each new Pi model release.
The official Raspberry Pi keyboard is available in Pi red and white and, soon, black and gray. The official Raspberry Pi mouse follows suit.
The design itself is a bit reminiscent of Apple, with a clean, minimalist scheme; the mouse even features a short cable, indicating that it's meant to plug directly into the keyboard to save desktop space, similar to older Apple keyboards.
The 79-key keyboard is currently only available in the U.K. keyboard layout but U.S., German, French, Italian, and Spanish layouts are coming soon.
The keyboard even features automatic keyboard language detection, which is neat! We all remember setting up a Pi for the first time and fumbling through the keyboard language menu so that we could input a symbol-laced Wi-Fi password.
The keyboard has three full-sized USB 2.0 ports built into its rear, as well as a Micro USB port for powering these ports. A removable matching Micro USB cable (included) is connected between this port and the Pi to provide data and power connectivity to the USB ports.
Of course, this is also where the USB mouse is connected.
The wired USB optical mouse is pretty standard; it features a scroll wheel and 3 buttons (left, right, and wheel click). The cord is very short as it is meant to plug directly into the keyboard.
If you're looking to buy the official Raspberry Pi keyboard and mouse, you can pick up the keyboard (£22.00 GBP), mouse (£ 7.30), or a bundle containing both (£22.00 GBP) over at The Pi Hut.
Note: Be sure to select the correct keyboard layout for your country, unless you really know your keyboard layout well. :) As of the time of this writing, only the U.K. layout is available.
