Miniature Wireless USB Keyboard with Touchpad
Add a miniature wireless controller to your computer project with this combination keyboard and touchpad. We found the smallest wireless USB keyboard available, a mere 6" x 2.4" x 0.5" (152mm x 59mm x 12.5mm)! It's small but usable to make a great accompaniment to a computer such as the Beagle Bone or Raspberry Pi.
The keyboard itself is battery powered (there's a rechargeable battery inside that you charge up via the included USB cable). The keyboard communicates back to the computer via 2.4 GHz wireless link (not Bluetooth)
