Adafruit Miniature Keyboard- Microcontroller-Friendly PS/2 and USB

Add a typing interface to your project with this microcontroller-friendly miniature keyboard. We found the smallest PS/2+USB keyboard available, a mere 8.75" x 4.65" x 0.6" (220mm x 118mm x 16mm)!It's small but usable to make a great accompaniment to either a microcontroller project or a computer such as the Beagle Bone or Raspberry Pi. The keyboard supports either USB or PS/2 interface and will automatically adjust to whichever it's plugged into (there's an adapter included).Comes with a full QWERTY keyboard, and has a num-lock number pad. Nearly all microcontrollers have existing PS/2 keyboard examples that would work fine with this keyboard.For Arduino users, we tried out PJRC's PS2Keyboard library with great success—just check the 'simple text' example for which pins you can connect to on your 'duino (on an Uno we used digital pins 2 and 3). We suggest our PS/2 adapter cable to make the wiring easy. Start typing and you'll see the data appear in the serial terminal!To use with a Raspberry Pi, change the keyboard to USA PC104 layout: Switch to the root user. Run 'dpkg-reconfigure locales' and change from enGB.UTF-8 to enUS.UTF-8. Run 'dpkg-reconfigure keyboard-configuration' and change the keyboard to USA PC104 (again, change as needed).
