If you don't need too much current over the cable than RJ45 is a good
connector. The pcb mounted connector should be available at most
electronic shops and you can just use finished network cables to connect
the device.
But be sure to use network cables which are specified for 1000MBit
because 10/100MBit only needs 4 wires and therefore many old cables
won't have all the 8 wires. ;)
