Description
 

Overview

The Rboard is a unique Arduino board which features 4 channels of isolated relays, an XBee socket, 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, and with everything on the same board, you'll save time by not having to wire it all up, and money by not having to buy individual modules.  



Features

  • 4 opto-coupler isolated channels
  • 4 mechanical relays with status indicator LED
  • Both “NC” and “NO” ports for each relay
  • ATMega328P with XBee interface headers, Micro SD socket
  • With Arduino Duemilanove bootloader

PWR_EXT Setting

The Rboard is designed for isolating industrial application with external power supply.  Remove the jumpers on PWR_EXT, and use the DC 7-20V terminal to power the ATMega328 and all digital circuit power supply.  Next, power the relay side by supplying the PWR_EXT terminal with 5V.  There are completely isolated power systems for controller side and relay side.

If you don't need stringent electrical isolation, put the jumpers on PWR_EXT, then you don't need an extra power supplies--the relays and controller will both be supplied by the DC 7-20V terminal.  There is also opto-isolation between the relay and controller I/Os.

Note

The RBoard does not have a USB con­nec­tion, a USB/Serial adapter is required to program the board.  If you don't already have one, the Foca FT232RL breakout board is a nice, inexpensive option.
