Specifications Top

This compact PS/2+USB keyboard available is 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 its 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 Ardiuno users, we tried out PJRC's PS2_Keyboard 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.

    Decent small keyboard

    Overall: 3.5 out of 5

    I bought this for use with a Raspberry Pi for mobile use and it is a decent little keyboard with a good feel to the keys. It is very lightweight and the housing feels sort of cheap, but I have had no problems with its durability. It is a bit cramped during use, but that is the trade-off for the compact size. This is about as small as I can go and still type semi-normally. The cord is thin and fairly long and I was able to easily shorten it by taking the bottom off the case and S-wrapping the cable back and forth inside the case to remove about 1.5' of length. Incidentally, the key section module is a fair bit smaller than the plastic housing and looks like it could be made even more compact. If you 3D printed a custom housing you could remove about 3/4" of length, probably 1" or more of width, and maybe 1/8" of thickness.
