Overview
With an on-board AC-DC module, Arduino IoTgo shield can transfer AC 110~250V to DC 5V, so it can be the power supply to arduino. Meanwhile, mainboards can control some home applications by setting the relays on this shield. Moreover, IoTgo shield has an Xbee interface and a Nrf24l01 interface. By using this shield, you can make some remote control home application projects with effortless.
