Punch Through's new Arduino board can stay wireless forever (video)

You'll have to plug in a typical Arduino-compatible board at some point in its life, whether it's to add code or just to supply power. Not Punch Through Design's upcoming Cortado, however. The tiny device centers on a custom Bluetooth 4.0 LE module that both enables wireless programming (including through mobile apps) and helps the board last for more than a year on a replaceable watch battery.
