Circuit Power Supply Driver Board PCB 6-14v Voltage Input for 445nm 520nm 3W Laser Diode LD Module

Circuit Power Supply Driver Board PCB 6-14v Voltage Input for 445nm 520nm 3W Laser Diode LD Module
Specification:
1.Dimensions : 10.2 * 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. It can drive 445nm 520nm 3W Laser Diode.

Package:
1x Circuit Power Supply Driver Board PCB 6-14v Voltage Input for 445nm 520nm 3W Laser Diode LD Module
