Objective:Raspberry Pi has a variety of networked ways, either via a wired network or via a wireless network. Through the wired network connection is relatively simple, in the DHCP-enabled router, directly plug in the network cable can be networked, this article introduces the way of the Raspberry Pi wireless networking. Without the network, if there is no screen

Installing the Raspberry Pi is only the first step in making Windows IoT core run on the Raspberry Pi, and the complete set of tools such as management systems are essential. Because Windows IoT core runs on a card PC, there are not too many UI actions set up, and many operations are done through the IoT dashboard app
