Description

For 445nm 520nm 2W Laser Diode 6-14V Power Supply Driver Circuit PCB Board
Specification:
1.Dimensions : 10.2 x 22mm ( W * L )
2.Circuit Control : 5V buck circuit , constant current output , 6-14V power supply to ensure stable output.
3.Reverse polarity protection : Unique reverse polarity protection design , do not worry about the battery polarity reverse making PCB board burnt.
4.Pin definition: especially designed for 445nm driver board, you need to weld LD pins to the PCB as per our instruction
5.Polarity definition: module casing is positive , tail of PCB is negative.
Feature:
1. In order to ensure safety, it is recommended to use good-quality 2pcs of 3.7V lithium batteries (16340,18650,14500 and 18500 battery), do not use low-quality batteries, or you can use 6-14V direct power supply.
2. This PCB board has no potentiometer to allow customers to adjust the current, it has fixed resistance.
