It is specially designed for low-voltage devices and works well under 3.3V power supplies, just like the Raspberry Pi relay board. In addition, the module has a wide range of power inputs. In our tests, once it reaches 2.8~5.5V, it can also support 1.8V devices.
DFRobot’s Digital Relay Module uses a high quality 3V relay. It can handle up to 10A current and mechanical parts are guaranteed up to 100 million uses. An on-board indicator LED demonstrates the relay’s state. Terminals include normally open (NO) and normally closed (NC). The module uses a Gravity-3 pin interface, which requires no soldering for convenient plug and play usage.

AustraliaExcellent Service and Quality part
Have ordered these a few times now, never had a fault with them. Very solid relay. Only downfall I could say would be that I’d prefer terminal connections rather than a plug (no one likes soldering when not needed) hahaGreat work guys
