The 1 Channel 5V Relay Module is designed to enable microcontrollers such as Arduino, ESP32, ESP8266, Raspberry Pi, STM32, and PIC controllers to switch high-voltage or high-current loads safely. Featuring a high-quality electromagnetic relay, transistor driver circuit, flyback protection diode, and LED status indicator, this module provides reliable and stable switching performance.

The relay can be used to control a wide range of electrical appliances, including lights, fans, pumps, motors, solenoid valves, and other AC or DC devices. Its opto-isolated design helps protect the control circuit from electrical noise and voltage spikes, making it suitable for both hobbyist and industrial applications.

With simple input and output terminals, the module is easy to connect and program, making it an excellent choice for automation and Internet of Things (IoT) projects.
