## Description

Introducing the Gravity Digital Relay Module – the latest addition to DFRobot’s [Gravity series](https://www.dfrobot.com/gravity.html)! This module is a little different to the other relays in our store - not only is it compatible with 5V [Arduino boards](https://core-electronics.com.au/arduino.html), but also with [Raspberry Pi](https://core-electronics.com.au/raspberry-pi.html), BBB (BeagleBoard Black), mbed, Intel Joule, Arduino 101 and other 3.3V devices.

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.
