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 7-20 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 7-20 terminal the same as controller part - but there also the opto-isolation between the relay and controller I/Os.
