The 2 Channel 5V Relay Module is a reliable dual-channel switching module designed to control two independent AC or DC electrical loads using low-voltage signals from microcontrollers such as Arduino, ESP32, ESP8266, Raspberry Pi, and STM32. It typically uses two SRD-05VDC-SL-C electromechanical relays, with each channel providing NO, NC, and COM terminals for flexible load switching. Onboard LED indicators provide clear relay status feedback, while the module's driver circuitry helps interface the relay coils with microcontroller GPIO pins.
