Default shipment is to drive 1W laser diodes. If you need to drive 2w or 3w laser diodes,please leave us message when you place an order.Thanks.!
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:
Notice: 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. default shipment for your orders without notes is to drive 1w laser diodes. If you are going to drive 1.6w, 2w or <3w Laser Diodes, please leave notes to us, we will send more stand-by resistance R200 with value 0.2 for you to use in order to drive 1.6W 2W laser diodes by welding 1-2 more resistance R200 with value 0.2 on the back of the existing R200 resistance on the PCB board
Package:
1x 445nm 520nm 1W 2W 3W Laser Diode Drive Driver Board PCB 6-14V Voltage Input Default shipment is to drive 1W laser diodes (default shipment is to drive 1W laser diodes)
