Pin Definition

Applications

This laser diode driver board is ideal for:

• 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

1. Apply 3.3–5.5V DC or GPIO high level to the EN pin.

2. Start from ADJ = 0V / PWM = 0%, then gradually increase brightness.

3. Do not reverse polarity or short output — may cause permanent damage.

4. Always wear certified laser safety goggles during operation.

5. Ensure proper cooling: use 40×40mm fan or heatsink with thermal pads.
