[Arm-netbook] Building your own keyboard

[Christopher Havel]

The '328 ones are Pro Minis, although eBay does tend to make a mess of the
labeling... both Pro Mini and Pro Micro designs are originally SparkFun
Electronics in-house designs. Great company, but I wish they hadn't done
those. I like the Arduino Nano (328) and original Micro (32u4) far better
than the Pro versions. You may have noticed! ;)

As an aside, the Micro and Pro Micro are really just shrink-ray'd Leonardo
boards. Whoo.
