RGB LED 모듈 -5V
(RGB LED Module -5V, Common Cathode)
개요
- 본 제품은 RGB LED 모듈입니다.
- RGB LED가 장착되어 있으며, 모듈에는 저항이 장착되어 있어 마이크로컨트롤러와 연결시 별도의 저항이 필요가 없습니다.
- PWM을 이용하여 R/G/B의 밝기를 제어할 수 있으며, 색상을 변화 시킬 수 있습니다.
특징
- the use of plug-in full-color LED
- RGB trichromatic limiting resistor to prevent burnout
- through the PWM adjusting three primary colors can be mixed to obtain different colors
- with a variety of single-chip interface
- the working voltage: 5V
- LED drive mode: common cathode driver
