## Questions & Answers

**Q: Is there a schematics for this relay board?**
A: No however it is an extremely simple board, they're really not necessary. Any drive voltage will do and it does have a transistor to switch the relay and a diode for protection.

**Q: I see from other question that the h (hi)  l (lo) is for active hi logic, or low active.. understood, but what about the dc+ and dc- ?? better documen**
A: This is to power the module. It needs 5VDC to operate

**Q: Would this work with 3.3v from a Due?**
A: No, the logic circuit would never see a digital high. You need a relay with 3/3.3V logic. I don’t know if FICBOX makes one, but there are other companies who do.

**Q: Is there any mounting hardware associated with these relays? i need to mount them on din rail.**
A: No. Nothing in the package except the relay boards.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Seems to work beautifully with LOW setting and simple ESP8266 01s
  

*by H***L on Reviewed in the United States on June 28, 2020*

I am using with no additional components or special wiring,  3.3 v, GPIO2 on the 01s web server. Will not work on "high" setting, of course. Time will tell! randomnerdtotorials is where I grabbed some basic web server code.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works great, no problems yet
  

*by A***R on Reviewed in the United States on February 9, 2019*

Currently using two of these and both are great. I couldn't figure out how to power a relay like this with a transistor, and for the price you can't beat it

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great value. Well-designed.
  

*by I***L on Reviewed in the United States on May 8, 2019*

I prefer the screw terminals but make sure you hold the terminal block with a small pliers as you tighten the screws. Don’t expect the solder to withstand a lot of torque, which is true of any product of this design.Also, what an incredible price for a product stocked in the US. Usually, I have to wait 4-6 weeks to get the same value from China-based outlets. I’ve only used one but the first one I picked did work. At this price I would be fine if one turns out to be inoperable, which should be fully expected nowadays.
