5mm red‑green dual‑color common cathode LED module with onboard current‑limiting resistor, for status indication and lighting experiment, compatible with Arduino, STM32, Raspberry Pi.
Description
Dual‑color LED Common Cathode Sensor Module
📌 Product Overview
This is a 5mm dual‑color red‑green LED common cathode module, adopting long‑leg two‑color LED lamp bead, supports independent control of red light and green light, can light single‑color or mixed‑color effect. Onboard current‑limiting resistor, no extra external resistor needed, easy to connect with MCU IO port for indicator light experiment, status prompt and light‑related project development. Compact PCB structure, lightweight design, 3‑pin pin header for quick wiring, suitable for Arduino, STM32, Raspberry Pi and other mainstream control boards.📋 Product Specifications
