Yes, you have to power the UC300ETH with 5Volts and you also have to power the HDBB2 with 12Volts.
Those voltages should not come from the same power source, but from separate power supplies, because the 5V is used to drive the logic of the UC300ETH and the 12Volts runs your sensors and switches etc. and so they should be isolated for safety.
