1 Channel 5V Relay Module
The 1 Channel 5V Relay Module is a reliable switching module designed to control high-voltage and high-current devices using low-voltage microcontrollers such as Arduino, ESP32, Raspberry Pi, AVR, PIC, and ARM boards. It provides electrical isolation between the control circuit and the load, making it ideal for home automation, industrial control, robotics, and IoT projects. The module allows you to safely switch AC or DC appliances with a simple digital signal.
