DockerPi 4 Channel Relay Hat Board

 


 [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 Raspberry Pi.
 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.
 
[Note]
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.
