MakerFocus Raspberry Pi Expansion Board 4 Channel Relay Board Module Power Relay Module for Raspberry Pi 4B/3 Model B+/Raspberry Pi 3/2 Model B (No Programming Required/Programmable)
The product operation guide can be obtained in the product guide and document. This Raspberry Pi expansion board supports Raspberry P.
The Relay Board gives your Raspberry Pi board the ability to control high voltage/high current devices, and easily makes normal home appliances become intelligent. Can be accessed programmatically or directly by shell. Up to 4 layers can be stacked..
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 4 Channel Relay uses high-quality relay modules combined with the most popular microcontroller technology to communicate with the Raspberry Pi. You can use mulitiple relay modules stacked together to add many channels.
The 4 Channel module is very fast, easy to install, and supports multi-language development, making it ideal for smart home projects.
