8 Channel 5V Relay Module
The 8 Channel 5V Relay Module is a versatile switching board designed to control high-voltage AC and DC devices using low-voltage microcontrollers such as Arduino, ESP32, ESP8266, Raspberry Pi, STM32, PIC, and AVR. Featuring eight independent relay channels with optocoupler isolation, this module provides safe and reliable control of appliances, motors, lights, pumps, solenoids, and home automation systems. Each relay can switch loads up to 10A, making it suitable for both DIY and industrial automation projects.
