DFRobot Gravity Digital Blue LED Light Module

DFRobot Gravity Digital Blue LED Light Module is a beginner-friendly blue LED module for Arduino-based electronics projects, featuring a bright, shiny blue LED and a standard 3-pin Gravity interface.

Overview

This module is designed for easy integration with an Arduino IO or sensor expansion shield, allowing hobbyists and students to add programmable lighting to their creations. Its plug-and-play design removes the need for complex wiring or soldering, making it suitable for educational settings, rapid prototyping, and embedded design development.

Low-Current Operation

The LED is wired to illuminate when the signal pin is set to LOW. This configuration helps prevent the LED from drawing excessive current from the microcontroller's pins, offering a safer and more reliable connection that helps protect the Arduino board.

Connection

The module uses a standardised 3-pin Gravity interface:

• Pin 1: Control Terminal (Signal)
• Pin 2: Power Supply (VCC)
• Pin 3: Ground (GND)

Applications

The module is suited to learning the fundamentals of digital output control, IoT (Internet of Things) device indicators, and interactive electronics projects. It can be used to build a status indicator, a decorative light, or an interactive art piece.

Dimensions and Weight

• Width: 3.3
• Depth: 1.5
• Height: 4.3
• Weight: 11 g

The compact, lightweight module provides a reliable and vivid lighting solution for Arduino starters and STEM learning.
