## Questions & Answers

**Q: Can the relay boards be stack? I.E. 2 boards stacked for a total of 6 relays, 3 boards stacked for 9 relays**
A: The default is relay 1 being on 26, 2 on 20, 3 on 21. These are all via jumpers. If you remove the jumpers you can connect GPIO pins to the posts for the relays via female-female wires. It looks like there is enough space to do this when they are stacked, too. My only concern would be stacking spacing. The relay board is about 2.5mm taller than the provided standoffs, so you would need additional spacers, and I’m not positive the GPIOs would be tall enough to connect.

**Q: Will this work with Raspberry Pi 4? Will it work with a 12v electronic air valve solenoid?**
A: Definitely.  I switch 120 V AC with it, so 12V is not a problem (it has opto-isolation to boot).  The Pi 4 will be functionally the same, but you'll likely be better off with the Pi 3 as it uses way less power. Do you need two displays ?

**Q: Is this product compatible with the Pi Zero W ?**
A: You must add a 40pin pin header connector for Pi Zero W

**Q: And how fast can the relays switch on and off?**
A: The spec sheet on the relay states that the operate time is 10ms Max and the release is 5ms Max. or roughly 15ms per cycle, or about 66Hz.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Well made, works with no problems
*by R***N on January 22, 2025*

Using this on my raspberry pi venus os project. Installed it tonight and git it programmed. Everything works as it should

### ⭐⭐⭐⭐⭐ Great for the price and takes a bit of tinkering(for the n00b) but it works perfectly!
*by J***N on May 20, 2019*

I'm an Arduino person and have a few RasPi's laying around and doing other things like OpenSprinkler but I wanted to start doing and playing around with a attic fan controller project. I'm getting into Python and other things and I've only had a few hrs to play with this since it just arrived but I used the demos and code that the Waveshare product has. Since I'm a noob on the RasPi/Linux stuff kinda it took a few more hrs (and that damn GoT finale got in my way!) but I was able to run all the sample codes, on/off tests, etc.The only one that I haven't played with or runs is the WebPioi thing but I think it was built for Pi2 and I'm running it on a 3B+ so I just need a night or a day to play with it.Overall, so far so good from this noobie. My goal is to a have a simple I2C temp sensor up in the attic and then once it hits a target temp, kick in the relay for the attic fan.I'll update later!

### ⭐⭐⭐⭐⭐ Decent relay output board with a few small quirks
*by M***T on January 3, 2019*

The good: Simple to assemble, works without any modification, good use of LEDs to indicate power and function.The bad: The mounting screws come installed and near their torque limit - with the proper screwdriver I stripped one mounting screw just trying to remove it. Using the mounting screws makes it difficult to find cases for the RPi & relay board combined.Overall - very good board for the price and I would buy it again.
