	*Arduino pins can put that out directly - 200mA for Vcc and GND pin - see [[Arduino Pin Current Limitations]]. Otherwise, the multiple output pins are rated for 20 mA, and 40 mA max. Since the signal for the relay can be small, the Vcc and GND connection is sufficient - but not if you want to power more than 3 relays simultaneously.		*Arduino pins can put that out directly - 200mA for Vcc and GND pin - see [[Arduino Pin Current Limitations]].
