🔍 Product Overview

The 4-Channel 5V Relay Module is a low-cost, high-utility interface board that allows your microcontroller (Arduino, ESP32, Raspberry Pi + ADC etc.) to switch multiple high-current loads. Each of the four channels features a driver relay designed to handle real-world AC or DC loads while being triggered safely with a 5 V logic signal.

🚀 Why It’s Ideal for Your Projects

• Expand control without complexity: You gain four independent channels to switch separate devices—all from one compact board.

• Plug-and-play with microcontrollers: With 5V logic inputs, you can directly interface with most hobby microcontroller boards without needing extra driver circuits.

• Ready for serious loads: Though intended for hobby use, such modules are commonly rated for loads like AC 250V or DC equivalent, enabling you to handle lamps, motors, relays, solenoids, and more.

📝 Key Features

• Four relay channels, each independently controllable.

• Trigger via 5 V logic input (so your microcontroller board can drive it directly).

• Each relay driver channel draws about 15–20mA for activation.

• Suitable for AC loads (e.g., up to ~250V) or DC loads depending on the module’s exact relay spec.

• Compact design making it ideal for embedding in control boxes, robotics platforms, or automation systems.

🎯 Typical Applications

• Home automation: Control lights, fans, pumps, or other appliances via your microcontroller.

• Robotics and mechatronics: Activate solenoids or motors when triggered by sensor logic.

• Remote / IoT projects: Use with WiFi/LoRa/ESP boards to switch power remotely.

• Prototyping: When you need multiple independent high-power switches in a compact setup.

✅ Why You’ll Love It

If you’ve been constrained by limited relay channels or had to build bulky driver circuits, this module gives you a clean, integrated solution. Four relays in one board, direct 5 V logic inputs, and a footprint that fits neat into hobby or semi-professional electronics projects—it bridges the gap between microcontroller signals and “real world” power switching with minimal hassle.
