5 customers mention5 positive0 negative

Customers find the relay versatile and useful for their projects. They say it's great for Arduino projects and prop controller projects, and a good relay block for small home automation projects. Some customers also use it for light control with a Raspberry Pi Zero.

"Great product for my light control with a raspberry Pi Zero" Read more

"Perfect for arduino prop controller projects!" Read more

"Good relay block for small home automation projects. I have used it for Arduino and Raspberry projects and works fine with both." Read more

"Great for Arduino projects and lots of other uses. High isolation and high voltage/power handling capability...." Read more

39 customers mention24 positive15 negative

Customers are mixed about the quality of the relay. Some mention it's very good quality, well built, and reliable, while others say that it has 1 bad relay and stopped working after a couple weeks of daytime use.

"This is a solid board that is easy to use. It can be triggered by either 3.3V or 5V Arduinos and probably most other controllers...." Read more

"...Also, it appears that the relay turns on with low voltage." Read more

"...] Great little relay module. Wired it right up and it worked on the first firing...." Read more

"...Construction: Well built." Read more

34 customers mention20 positive14 negative

Customers are mixed about the ease of use of the relay. Some mention that it works every time, is super-easy to integrate with an Arduino-type device, and is a cheap and easy way to interface with anything you want to turn on. However, others say that there's a lack of documentation for the inexperienced on wiring configurations and instructions from the manufacturer. Some say the schematic is missing and the directions could be much better. Overall, the product does require a certain knowledge base and is plug and play.

"...from the GPIO pins which protects the Pi and means that this board is plug and play...." Read more

"1 star off for no documentation but otherwise a very cost effective relay board. Provides optical isolation and some degree of physical isolation...." Read more

"This is a solid board that is easy to use. It can be triggered by either 3.3V or 5V Arduinos and probably most other controllers...." Read more

"...The rest were very straightforward....simply hook a GPIO to each of the ports and off you go...." Read more

7 customers mention4 positive3 negative

Customers are mixed about the indicator. Some mention it's a nice setup with indicating LEDs built in, and it shows the state for each relay. However, others say that the indicator LED is missing, the status LED was DOA, and the LEDs on the relay board are dimly lit.

"...thing that I thought was really really nice is that there is a built in LED indicator of which ones are activated and which aren't...." Read more

"...The LEDs on the relay board are dimly lit which suggests there are pull-down resistors in operation...." Read more

"Works really fine. and it also shows with onboard SMD LEDs the state for each relay...." Read more

"...figure out when Relay1 didn't work before I noticed that the indicator LED is missing...." Read more

12 customers mention0 positive12 negative

Customers are dissatisfied with the pins of the relay. They mention that the headers were bent, the product was damaged, and the led was broken off. Some customers also report that the pin sticks out of the bag.

"...the GPIO library (under Python) or shutdown the Pi, the GPIO pins are floating - this leads to undesirable relay chatter without the pull-downs...." Read more

"Delivery: Mine arrived with three pins bent, sticking out of the plastic wrapper...." Read more

"...As best as I can tell, the led was broken off...it just wasn't installed." Read more

"Opened the package to find that ALL of the pins had been bent..." Read more

1 star off for no documentation but otherwise a very cost effective relay board. Provides optical isolation and some degree of physical isolation. I would judge this board suitable for light-duty AC Mains usage. The unit works well with my Raspberry Pi 2 and Pi 3. I will be buying more.Addendum for Pi users. When the Pi first boots the GPIO pins are not yet defined as outputs. The LEDs on the relay board are dimly lit which suggests there are pull-down resistors in operation. However, once you define the GPIO pins as outputs the relays immediately switch on. You can turn off the relays by sending the GPIO output high (GPIO.output(xx, True) where xx is the corresponding pin number).To resolve these issues I decided to add inverters between the GPIO pins and the relay card. For this I chose a quad, 2-input schmitt NAND gate device (4093B). I also added pull-down resistors (47k ohm) to the 4093B inputs because when you cleanup the GPIO library (under Python) or shutdown the Pi, the GPIO pins are floating - this leads to undesirable relay chatter without the pull-downs. You can power the 4093B from the 3.3V power supply on the Pi's interface. You can probably substitute a 4011 Quad NAND for the 4093 but I haven't tried it. The picture shows my inverter card which solders direct to the relay card.Using GPIO pins 23 through 26 the code to initialize then turn on relays 1 and 3 would look something like this:import RPi.GPIO as GPGP.setmode(GP.BCM)GP.setup([23,24,25,26], GP.OUT)GP.output([23,24,25,26], [True, False, True, False])...to turn on / off relay 2 would be:GP.output(24, True)GP.output(24, False)...GP.cleanup()

GP.setup([23,24,25,26], GP.OUT)
GP.output([23,24,25,26], [True, False, True, False])
...
to turn on / off relay 2 would be:
GP.output(24, True)
GP.output(24, False)
...
GP.cleanup()
