Four relay with module

A Four Relay Module is a versatile electronic switching board that allows a microcontroller such as Arduino, ESP32, or Raspberry Pi to control four separate electrical devices. Each relay works as an electrically isolated switch, making it suitable for controlling lights, motors, fans, pumps, solenoids, and other AC/DC loads. Key Features: 4 independent relay channels Easy interface with Arduino, ESP32, and other controllers Supports NO (Normally Open), NC (Normally Closed), and COM terminals LED indicators for relay status Suitable for automation and robotics projects Compact and easy-to-use module Useful for controlling multiple devices simultaneously
