The 5V 1-Channel Relay Board Module provides a simple way to switch high-voltage loads from your Arduino, Raspberry Pi, or other microcontroller project. Controlled via a 5–12V TTL signal, this relay can switch loads up to 250V AC, making it suitable for controlling lights, fans, pumps, and other mains-powered devices.

The board includes an onboard LED power indicator and screw terminals for easy wiring of the relay output.

Key Features

  • 5–12V TTL Control – Compatible with 5V and 3.3V logic microcontrollers
  • Switching Capacity – Up to 250V AC / 10A
  • Screw Terminals – NO, COM, and NC relay outputs for easy connection
  • LED Indicator – Onboard power indicator for quick status check
  • Songle SRD-05VDC-SL-C Relay – Reliable, widely used relay

Ideal For

  • Arduino and Raspberry Pi home automation projects
  • Switching lights, fans, pumps, and solenoids
  • IoT devices requiring mains-voltage control
  • Prototyping industrial control systems

Package Contents

  • 1× 5V 1-Channel Relay Board Module
Warning: This module switches mains voltage. Ensure all high-voltage wiring is performed by a qualified person and that connections are properly insulated.
Need more channels? See also the 2-Channel, 4-Channel, 8-Channel, and 16-Channel relay modules, or the Optocoupler Relay Module for isolated control.

Resources

Jargon buster

Plain-language definitions for the technical terms used above.

IoT
Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
LED
A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
microcontroller
A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
