Xboard Relay – An Ethernet Controllered Relay

Internet of things has become so easy.  With Xboard Relay, you can not only monitor data through internet, but also control it through internet.  The Xboard Relay combines an Atmega 32u4 microprocessor and wiz5100 chip which is fully compatible with Arduino Lendardo and Ethernet library, it has build-in  Xbee socket and 2 Relays which allow an easy sensoring and controlling over internet.
