## Description

Description 4 Channel Relay Hat Board For Raspberry Pi is one of the "docker pi" module.  It has 4 channel relay that you can put it on your smart home project.  This four-channel relay uses high-quality relay modules combined with the most popular microcontroller technology to communicate with the Pi board.  You can use multiple modules stacked together for use.  You can stack up to four layers.  Switch the I2C address of the device through the DIP switch on the circuit board to ensure that the four-layer module gets different addresses, thus avoiding the problem of address duplication.  The module is very fast, easy to install, and supports multi-language development, making it ideal for smart home projects.  PS： The 4pin pin is a backup that supplies power to future products. You can ignore those pins. Please do not connect any device to that pins.  Features Easy to use 4 channel relay Support I2C protocol Support for stacking Support address switching by dial switch Support multi-language programming Support 3A 250V AC Support 3A 30V DC Support relay status light prompt Package include 1x 4 Channel Relay Hat Board 4x M2.5x11+6 copper stick 8x M2.5x5 screws & nuts 1x Instructions Wiki:https://wiki.52pi.com/index.php/DockerPi_4_Channel_Relay_SKU:_EP-0099

## Questions & Answers

**Q: Is a 3A relay enough for home heatpump and airconditioning?**
A: Not if u use it to switch the compressor. yes if its just for the thermostat

**Q: Is it possible to connect an i2c  (si7021 temp/humidity sensor) to the i2c pins 3 and 5 when using this hat?**
A: As this board can be stacked, it has male pins on top, so you definitely physically can connect something to the pins. I guess you'll only need to take care of the I2C address you use to not interfere with the ones of the relay board(s)

**Q: Does this board have optocouplers to prevent high voltage interference?**
A: Dont think so.  I wouldn't use it for high voltage anyway.  See my review

**Q: Can i use gpio pins for inputs and use the relay board too?**
A: Yes you can.
