The 5V 4-Channel Relay Module is a versatile switching module designed to allow microcontrollers and low-voltage control systems to safely switch multiple electrical loads. It features four independent relay channels, enabling users to control several devices from a single module.
The module can be easily interfaced with popular development boards such as Arduino, Raspberry Pi, ESP32, and other compatible microcontrollers. It is ideal for automation projects where a low-voltage control signal is used to operate higher-voltage or higher-current loads within the relay's rated specifications.
