This wireless keyboard with a touchpad adds a miniature wireless controller to your computer project with the combination of the keyboard with the touchpad. It's small but usable to make a great accompaniment to a computer such as the Raspberry Pi. In addition, it is also compatible with multi-systems thus it can run on Windows, Mac, Android, and Linux. The keyboard itself is battery powered (there's a rechargeable battery inside that you can charge via the included USB cable). The keyboard communicates back to the computer via 2.4 GHz wireless link (not Bluetooth), with a universal 2.4Ghz USB dongle.
