This is a fantastic product at a great price. Just one thing! Do NOT set the jumper to GND-VCC! This will cause a short! This is not a design error! You can use the board non-isolated the way it comes.
This jumper is used to separate the opto-coupler circuit from the relay side.
To fully isolate the inputs from the relays:

1) Pull the jumper and use secondary 5 volt power to the relay using GND and VCC next to JD-VCC. Do NOT use the VCC and GND pins next to the IN1 and IN8 input pins!
2) The JD-Vcc is the common for all inputs. The input side consists of the indicator LED and opto-coupler-LED and a 100 ohm resistor in series.
3) Apply Arduino 5 volt to JD-VCC and IN1 or INx to the Arduino outputs (LOW) and the relay will be triggered. Hope this helps! Thanks to Eric for the schematic! You can find a schematic on amazon.

This board is really cheap and does exactly what it has to. I am currently using mine for my raspberry pi and have found no issues. Highly recommend it.

Dear all

I am using a Leonardo and would like to use this relay board to switch contactors in a high power application.

i am a bit cautious to use this device as it uses active low TTL.
in other words, a low on my arduino pin switches the relay on.
do the relays switch on during reboot/startup ?
apparently the arduino forces the outputs to high impedance during boot. is this true ?

if anybody could give me some advice here or a different product that uses active high TTL . i would truly appreciate it.

many thanks

Well in the search for a DIY solution for my custom freshwater aquarium projects, research led me to this product. Currently I am interfacing this 8 channel version with a Beagle Bone Black and soon will be adding another 8 channel module that will be interfaced with an Arduino Uno R3 and probably more to come These thing's a are extremely easy to hookup and program. I am looking forward to when I have these in production, automating many of the features of my aquariums. There are many free resources on YouTube.com on how to interface these modules with many controllers. Thanks SainSmart for providing a product that does what it does, and does it well! ;)
Although advertised for use with the Raspberry Pi, they work with just about any 3.3v-5v based micro-controller. You can even power them via separate power supply to completely isolate your power between your high voltage side and your micro-controller if you’re worried about things in that aspect.
Highly recommended for DIY projects that need basic digital on/off control of outlets! The only caveat is there is no documentation provided, but like I said, YouTube.com and a few web searches brings a vast amount of free knowledge on these modules.

This is a fantastic thing to have with Arduino. I honestly only bought this because I had a gift card and it looked semi interesting but I have really kept myself entertained with it. No regrets. Hook the relay boards VCC to the +5 on the Arduino, the boards GND to the Arduinos Ground and then just use simple HIGH and LOW digital pin states in Arduino with the board pins. Each relay has three terminals. One input terminal and the other two are for a normal-open output and closed output making this pretty versatile. The relays are very fast too. I wouldn't try to switch them below 40ms though (the fast parts in the video are 46ms on/off) since that may cause some wear or you may get some bad switching. These would be great for a christmas light setup if you're in to that. I still haven't figured out what I want to do with this in the long run but it is very cool and I can see a lot of potential in it. For now I just decided to make a quick sketch to a song (using only HIGH/LOW pin states and delays). I think I'll hook it up to some lights or something eventually.

The relays I got are fine, price is great. However, even though I can get the documentation online, but it would be better if it has paper along with the product.
