Channel Module Arduino Raspberry Devbattles Review

Is there a no star rating? There is one that worked for a minute. Went back and got another one that was DOA. Thank goodness for Revain's return policy. Will avoid products sold by devbattles in the future.

None of the devices are working. There was no documentation for the product so I appreciate the importance of the label. Two days ago I requested documentation from the manufacturer via Revain, but have not yet received a response. I will return them.

I did not have the opportunity to test channel 1 before the return deadline. So I ordered a replacement from another seller. The replacement works great and comes in the official Sunfounder box. I think this particular product may not be an official Sunfounder product. Based on my experience and other reviews, I would not recommend buying it.

This was exactly what I was looking for in terms of features and connectivity. Unfortunately relay 1 did not trigger high or low. Relay 2 worked fine. Sent it in for exchange, new is the same. Also, even though it says 5 volts on it, it's actually a 12 volt device. I was able to get it working for my application so I kept the spare.

The product description says "1-channel DC 5V relay module for Arduino". I soldered it into my circuit assuming that's what it says and it didn't work. Then I realized it was for 12V DC, not 5. Waste of time and money, now I have to desolder everything and start with a new part.
