Difference between 5V Relay module and Grove Relay

Hi There, I am looking for a relay to switch a 110V Water Heater. I have brought a Grove Relay (http://www.seeedstudio.com/depot/grove-relay-p-769.html). What is the difference between that unit and the 5V Relay module (http://www.seeedstudio.com/depot/electronic-brick-5v-relay-module-digital-p-479.html)

Thanks in advance,

:slight_smile: Just the difference of limit work voltage and current , and the different interface. Both they can be used to you 110VAC Water Heater under 10A current.


Thanks got it setup to work fine!
