1-Channel 5V Relay Module (Low-Level Trigger)

Easily control high-voltage appliance circuits directly from your microcontroller!

Whether you're building a smart home automation system, a custom IoT project, or an industrial control setup, this 5V Single-Channel Relay Module bridges the gap between low-power microcontrollers and high-power electrical loads.

Designed with an active-low trigger, it allows microcontrollers like Arduino, Raspberry Pi, ESP8266, and ESP32 to safely toggle lamps, motors, solenoids, and AC appliances up to 10A.

Key Features & Benefits

High-Power Switching: Safely switches loads up to 250V AC / 10A or 30V DC / 10A.
Low-Level Trigger: Activates when the control pin is pulled to GND (0V), making it ideal for standard microcontroller outputs.
Onboard LED Indicators: Features a power indicator LED alongside a dedicated relay state LED for real-time diagnostic status.
Easy Terminal Connections: Comes equipped with heavy-duty screw terminals (NO, COM, NC) for effortless load wiring without soldering.
Universal Compatibility: Works seamlessly with Arduino, ESP8266/ESP32, Raspberry Pi, PIC, AVR, and 8051 platforms.
