I’ve been looking for a compact wireless keyboard and mouse for use with my Raspberry Pi and think I’ve just found the ideal solution. The Perixx Periduo-707 Plus is a very compact wireless keyboard that measures just 320mm x 140mm. It has full size keys but saves space by not having a dedicated number pad. The 707 Plus comes with a compact wireless optical mouse and both the keyboard and mouse use a couple of AAA batteries for power.
The connection to the computer is via a tiny 2.4GHz wireless dongle that was automatically recognised by the Pi.
Both mouse and keyboard are solidly built and are working very well for me.
The Periduo-707 Plus is available with a black or white finished and costs around £20 to £25.
