The circuit board is a precision component. After receiving the package, it supports 7 days without reason to return the product without opening the original package. After the original package is opened, no return is provided. After sale, please consider whether you have the ability to install it manually before purchasing. Do not purchase if you do not have the ability to install! Our company does not provide trial play/trial loan/trial service. Thank you for understanding!

• 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.
