DevLab: G6K-2G-Y-TR 5V Relay Module

What is it?

The DevLab: G6K-2G-Y-TR 5V Relay Module is a compact and reliable switching module designed to control high-voltage or high-current loads from low-voltage microcontrollers and development boards. It enables safe and efficient control of external devices such as motors, lights, pumps, solenoids, and appliances, providing electrical isolation between the control logic and power outputs. With two independent channels, this module offers flexible and precise control for automation, IoT, and embedded system applications.

Why did we make it?

We developed DevLab: G6K-2G-Y-TR 5V Relay Module to simplify the integration of high-power devices into low-voltage systems. Many developers struggle with safely controlling AC or DC loads using microcontrollers like Arduino, ESP32, or Raspberry Pi due to voltage mismatch and safety concerns. This module acts as a secure interface, allowing developers to focus on innovation without worrying about damaging their main control board or compromising electrical safety.

What makes it special?

• 2 Independent Relay Channels
• Control two separate devices or circuits simultaneously with full electrical isolation.
• Opto-isolated input design
• Protects your microcontroller from voltage spikes and interference coming from the load side.
• 3.3V & 5V Logic Compatible
• Works seamlessly with Arduino, ESP32, RP2040, STM32, Raspberry Pi, and other common platforms.
• NO & NC Output Configuration
• Supports Normally Open (NO) and Normally Closed (NC) terminals, enabling versatile switching behaviors.
• Status Indicator LEDs
• Visual LEDs provide real-time feedback of power and relay activation status—perfect for debugging and monitoring.
• Compact & Lightweight Design
• Optimized for easy mounting in compact enclosures and embedded projects.

This module is ideal for smart home systems, industrial automation, robotics, irrigation controllers, security systems, and educational projects.
