Keyestudio 4-channel 5V Relay Module for Arduino

The Keyestudio 4-channel 5V Relay Module for Arduino is a versatile switching interface designed to let low-power microcontrollers safely control high-current appliances. It is ideal for South African students, makers, and hobbyists looking to integrate real-world devices like lights and motors into their automation projects.

High-power load switching

This module features four independent channels capable of switching AC loads up to 250V at 10A or DC loads up to 24V at 10A. It allows your low-voltage microcontroller projects to safely control high-power devices such as household lights and electric motors.

Visual status indicators

Each channel is equipped with a luminous diode that acts as an onboard LED indicator. This provides immediate visual feedback on the output state of each relay, making debugging and system monitoring straightforward.

Modularised Arduino integration

Designed with a modularised layout, this board connects easily to Arduino expansion shields. It operates using standard TTL voltage control signals, making it highly compatible with standard microcontroller development platforms.

Clear pin definitions

The module features a simple interface consisting of four control pins (Pin 1 to Pin 4), a VCC power supply pin, and a GND ground pin. It supports both Normally Open connections up to 10A and Normally Closed connections up to 5A.

Comprehensive learning resources

To help educators and hobbyists get started quickly, the module is fully supported by Arduino software and an online wiki tutorial. This ensures a smooth setup process when writing control code for your automation projects.
