• Install the laser diode on the PCB and solder the three pins. Connect the positive and negative poles on the PCB to 3-5V DC, and VCC is the positive pole.
• Current:70mA  
• Input voltage:2.7-5.0V
• Output Voltage:2-5V
• Use the potentiometer to adjust the output power of the laser diode. If the diode can only withstand low current, you must first adjust the potentiometer to the minimum current and then adjust the diode to the required output power.

Note: The laser diode needs to have good heat dissipation to ensure the normal operation, and the circuit will automatically control the light output power of the laser diode.
