Keyestudio 2-channel 5V Relay Module for Arduino ARM PIC AVR DSP Electronic

This Keyestudio 2-channel 5V relay module is a versatile switching solution designed to control high-current loads from low-power microcontrollers. It is ideal for South African makers, students, and hobbyists looking to safely interface Arduino, ARM, PIC, AVR, or DSP systems with mains-voltage appliances or heavy DC motors.

Dual-channel high-current switching

This module features two independent input and output channels, allowing you to control two separate electrical circuits simultaneously. It supports loads up to 250V/10A AC or 24V/10A DC, making it perfect for controlling household lights and domestic motors.

Modular design for easy integration

The modularised layout ensures straightforward connection to Arduino expansion boards and other development platforms. This simplifies prototyping and reduces wiring clutter in your robotics and home automation projects.

Visual status indicators

Onboard LEDs provide immediate visual feedback by displaying the current output state of each relay channel. This makes debugging and real-time monitoring convenient during testing and deployment.

Electrical specifications and pinout

Driven by TTL voltage control signals, the module features a rated load capacity of up to 10A at 250VAC or 30VDC, with a rated through-current of 10A for normally open and 5A for normally closed contacts. The board includes dedicated pins for power supply, ground, and the controlling ends.
