Gravity 16A Relay Module 3.3-5V Logic Compatible

This is a 16A relay from DFRrobot. The relay module was specially developed for low voltage devices and operates without problems in a voltage range from 3.3V to 5.5V. A relay is an electrically operated switch that is used for switching on, off, and changing of circuits. The 16A relay module can be used in interactive projects. It can also be used to control lighting, electrical and other devices. It can be controlled via the digital IO port and is suitable for switching, for example, solenoid valves, lamps, motors. 

For safety reasons you should only operate the relays up to 30V, as the back of the PCB is not isolated and careless handling with 230V can be dangerous.
