Hi, Has anyone had success using arduino relays with RXs? I am looking for an alternative pump switch for my cruiser and came across this guy. The coil triggers off 5v, and it can switch 10a at 12v, which should be plenty for a cruiser. Do you think this would work? It is 2.50€ (About 3 dollars)). Would the signal from a RX running from a 4.8v battery be enough to trigger it?
