Itead RBoard Arduino Relay Wireless

Rboard is a unique Arduino board which features 4 channels isolated relays, an XBee socket (xbee available separately ), and an ATMega328. This board will add relay control as well as wireless connectivity to your projects. It’s great for anything from home automation to robot control. The possibilities are endless!

4 channel relays with photocouple isolated, Micro-SD Socket, XBee interface, nRF24L01+ interface, many analog/digital electronic brick interfaces and so on, many interfaces are designed and broke out for many projects as wireless communication, mass storage, digital control and signal sample.

PWR_EXT Setting

Rboard is designed for isolating industrial application with external power supply. So when remove the jumpers on PWR_EXT, use the DC 7-12 terminal to for ATMega328 and all digital circuit power supply, and supply the 5V relay by the PWR_EXT terminal with 5V, there are 2 completely isolated power systems for controller part and relay part.

If you don't need so stringent electrical isolation, put the jumpers on PWR_EXT, then you don't need an extra power supply, the relays will supply by the DC 7-12 terminal the same as controller part - but there also the opto-isolation between the relay and controller I/Os.
