HS-F08B Yellow LED Indicator Module – 3.3V/5V Ready
HS-F08B Yellow LED Signal Indicator Module – 3.3V/5V Ready
The HS-F08B is a compact, ready-to-use yellow LED indicator module designed for quick visual feedback in electronics projects. It accepts a standard 3.3V or 5V digital input, lighting the onboard LED when the signal is HIGH. With a built-in current-limiting resistor, it simplifies connections and ensures safe operation with most microcontrollers.

What You Can Build With This
- Add a power-on or status LED to any breadboard prototype.
- Construct a simple logic probe for debugging TTL or CMOS circuits.
- Use multiple modules to indicate the output state of a home automation controller.
- Create a visual alert system that lights up when a sensor threshold is crossed.
Compatibility
This indicator module works seamlessly with Arduino, Raspberry Pi, ESP8266, ESP32, and any microcontroller offering a 3.3V or 5V digital output pin. It pairs directly with sensor breakout boards to show trigger events without additional components.
Wiring Notes
Connect the VCC pin to your system’s 3.3V or 5V power, GND to common ground, and the IN pin to a digital I/O line. When the pin is set HIGH, the LED illuminates. No external resistor is required—just three simple connections.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Uno?
Yes, the HS-F08B includes a current-limiting resistor sized for 5V operation, allowing direct connection to any Arduino Uno digital pin.
How bright is the yellow LED?
The LED emits a typical brightness of 100 mcd, making it clearly visible indoors for status indication without being overpowering.
Can I use multiple modules on the same board?
Absolutely—each module operates independently. Connect several IN pins to different microcontroller outputs to build a multi‑LED indicator panel.
