Leonardo + Ethernet V2

Leonardo with Ethernet
The Leonardo + Ethernet(V2) is the best decision for creating anything internet-related. The device is created on the bases that the controller can play a role of a fully functional net member. As a net member role, the Leonardo + Ethernet(V2) can gather data from different devices or industrial equipment and send gathered data through local network or internet. The Leonardo + Ethernet(V2) is a fully functional Ethernet-device and can assume the position of server, receive queries from other NET devices and services in local network and internet, and answer those queries. It can also act as self-contained unit, capable of autonomous reaction in response to changes in network, according to planned algorithm.The board unites two controllers: Leonardo on base of ATmega32U4 microcontroller and Net-controller Ethernet WizNet W5500 TCP/IP with optional function PoE (receiving power directly through Ethernet cable). The Leonardo + Ethernet(V2) is also a HID device. It can be used as a mouse or keyboard on the connected computer, in addition to (CDC) sequenced/COM-port. You can program the controller so that it can control the application on your PC, through remote access or through the internet as a NET device. For example: you can set up an algorithm that turns on your PC, opens and controls applications. The board itself can open Arduino IDE, open sketches and upload it to the board.
