This unit is advertised as being the size of a credit card. Although it is slightly larger than a credit card, it is quite powerful and versatile for small applications such as hobby devices and home-theater networks. This device runs on a Linux system that is tailored specifically for it. All told, I am very happy with this device, so much so that I bought a second one within a month.
Excellent Computer
