The DFRobot Relay Module is a standard relay used with a controller board to interface external electrical circuits or modules. Some of the most common applications with Arduino are: Home lighting, electrical appliances of high power and other equipments.
The modular design makes it easy to integrate with a controller board. The Relay integrates a status LED, in order to acknowledge visually it's status ON or OFF. It can be controlled through the digital IO port, with a simple HIGH or LOW on Arduino compatible boards. Other boards will work requiring same voltage level. Other usages include control of solenoid valves, lamps, motors and other high current or high voltage. devices.

Gravity: Digital 5A Relay Module
The Relay Module is well made and works well with the supplied cable. If you don't want to use 3 consecutive header pins, extension jumpers could be used with it. I've been using a 3 channel relay until now but for this project only needed 1 channel and this is perfect for the job.

Gravity: Digital 5A Relay Module
I bought this item to trigger lighting in my home with my Raspberry Pi Zero W. I use Gnd, 5V and an output pin for triggering this relay and works as expected. For me the LED on the relay's PCB is too bright and seems to be unnecessary. What I could not figure out what plastic case I could use for this relay so that the high voltage is insulated appropriately, so currently I am only triggering 12VDC lighting with it

Gravity: Digital 5A Relay Module
I bought it to control a garage door using my RPi ZeroW hoping that it would work without additional circuitry)! It worked perfectly at the first try even though the RPi GPIOs are only 3.3V and the relay's control signal is specified as TTL (5V). The built in transistor makes the direct interface to the RPi easy. Not sure if the 3.3V control signal support is intentional but at least it works for me (might not work in other setups).
