Easy to connect to Arduino board as it is 5V logic. There are 3 Leds, 1 green to indicate the module is powered, the 2 reds to indicate the relays are switched on. It has screw terminals on the logic side as well: you can screw any kind of wire for the command, if you find pin connectors too restrictive. Soldering are ok.
