The Soofa Sign is wireless and runs entirely off the solar panel on its top - which means that installation is truly plug-and-play and hassle-free as it only requires four bolts. The display itself is a 32" color E Ink panel. Soofa is now installing signs in Boston, MA - and will soon expand to other cities in the US.
