Pin Definition
| Pin | Function | Voltage Range | Notes |
|---|---|---|---|
| EN | Enable (High = ON) | 3.3–5V | For emergency/test use only; series resistor 5–10K required |
| ADJ | Analog Brightness Control | 0–1.2V | Do not exceed 1.2V; minimum 0.2V required to turn on |
| PWM | Digital Brightness Control | 3.3V / 5V logic | Supports 0–100% duty cycle, 5–20kHz frequency |
| GND | Signal Ground | 0V Reference | Must be connected to controller ground |
Applications
- Mini laser projectors & light engines
- Biomedical laser excitation & sample detection
- UV curing LED & laser light sources
- Automotive laser headlights
- High-power LED lighting (RV, industrial, outdoor)
Safety Notes
- Apply 3.3–5.5V DC or GPIO high level to the EN pin.
- Start from ADJ = 0V / PWM = 0%, then gradually increase brightness.
- Do not reverse polarity or short output; may cause permanent damage.
- Always wear certified laser safety goggles during operation.
- Ensure proper cooling: 40×40mm fan or heatsink with thermal pads.
