4. Working Principle
The module operates based on digital signal control:
- Power Connection: The module connects to a power supply via GND and VCC ports, operating within 3.3V to 5V to ensure proper functionality.
- Signal Control: The signal pins (R, G, B) receive input signals from a controller to control the states of the red, green, and blue LEDs, enabling color output.
- PWM Dimming: Supports Pulse Width Modulation (PWM) technology, allowing users to adjust the brightness of each color channel for mixed-color effects.
- Connection Configuration: The red anti-reverse connector and matching cable ensure safe and efficient connections, reducing the risk of wiring errors.

5. Pin Description
| Pin Name | Description |
|----------|---------------------------------------------------|
| VCC | Positive power supply (3.3V to 5V input) |
| GND | Negative power supply connection |
| R | Control signal for the red LED |
| G | Control signal for the green LED |
| B | Control signal for the blue LED |

- VCC: Connects to the positive terminal of the power supply. Ensure the voltage remains within 3.3V–5V to prevent damage.
- GND: Connects to the negative terminal (ground) of the power supply for stable operation.
- R (Red Signal Pin): Controls the red LED (high level turns it on).
- G (Green Signal Pin): Controls the green LED (high level turns it on).
- B (Blue Signal Pin): Controls the blue LED (high level turns it on).
