1 Channel 5V Relay Module (Low Level Trigger)

The 1 Channel 5V Relay Module (Low Level Trigger) is a reliable and easy-to-use switching module designed for controlling high-voltage or high-current devices using low-voltage microcontrollers.

Featuring a low-level trigger design, the relay is activated when the control input receives a LOW signal, making it compatible with Arduino, ESP32, Raspberry Pi, STM32, and other development boards.

The module includes onboard indicator LEDs, transistor driver circuitry, and isolation components to ensure stable and safe operation. It allows low-power control systems to switch larger AC or DC loads such as lights, fans, pumps, motors, and home appliances.

Its compact design and simple interface make it ideal for automation projects, smart home systems, robotics, and industrial control applications.
