4. Working Principle
The LED module operates based on digital signal control. Its working principle is as follows:
- Power Connection: The module connects to a power supply via GND and VCC ports, supporting an operating voltage range of 3.3V to 5V. A stable power connection ensures proper LED functionality.
- Signal Control: The signal pin (S) receives input from a controller. A high-level signal turns the LED on, while a low-level signal turns it off.
- PWM Dimming: Supports Pulse Width Modulation (PWM) technology, allowing users to adjust brightness by modulating the signal duty cycle. This enables effects like gradual brightening/dimming or breathing lights.
- Connection Configuration: The module's design facilitates quick assembly and disassembly. The red anti-reverse connector and matching cable ensure safe and efficient connections, minimizing damage risks from incorrect wiring.

5. Pin Description
| Pin Name | Description |
|----------|---------------------------------------------------|
| VCC | Positive power supply (3.3V to 5V input) |
| GND | Negative power supply connection |
| S | Signal input pin for controlling LED on/off states|

- VCC: Connects to the positive terminal of the power supply. Ensure the voltage remains within 3.3V–5V to prevent module damage.
- GND: Connects to the negative terminal (ground) of the power supply, establishing a stable reference voltage.
- S (Signal Pin): Receives control signals from a microcontroller. A high-level signal activates the LED, while a low-level signal deactivates it. Users can program this pin according to project requirements.
