Frequently Asked Questions (FAQ)
Q1: Can I drive this LED directly from a GPIO pin?
A: Yes. The onboard transistor allows you to safely drive the LED using a logic-level HIGH signal from a GPIO pin.
Q2: Is this compatible with 3.3V microcontrollers?
A: Absolutely. It works with both 3.3V and 5V systems.
Q3: Does the LED turn on with active HIGH or LOW?
A: The module is active HIGH – send a HIGH signal to SIG to turn on the LED.
Q4: Can I change the color of the LED?
A: This version comes with a white LED. Color customization would require swapping the LED manually.
