HW-479 Clear LED Module – 3-Pin LED Indicator Board for Arduino & Microcontrollers

The HW-479 Clear LED Module is a compact, easy-to-use LED indicator board designed for microcontroller projects, learning kits, and rapid prototyping. Featuring a clear LED mounted on a small PCB with built-in current-limiting resistors, this module allows safe and direct connection to popular development platforms without additional components.

With its 3-pin interface (VCC, GND, Signal), the HW-479 can be driven by digital I/O pins for simple on/off indication, PWM brightness control, or status signaling. The clear LED provides bright, neutral illumination suitable for visual feedback in debugging, demos, and educational experiments. Its standard 2.54 mm header spacing ensures compatibility with breadboards, jumper wires, and common microcontroller headers.

Ideal for Arduino projects, STEM education, and electronics labs, this LED module simplifies wiring, reduces setup time, and improves reliability for indicator and notification use cases.

 
Key Features:

• Clear LED with onboard resistor – Safe, direct connection to logic pins without external current limiting.
• 3-pin interface (VCC, GND, Signal) – Simple wiring for digital control and PWM brightness adjustment.
