445nm 447nm 450nm 1W 1.4W 1.6W Laser Diode Drive/Driver 3.7V 9x20mm

Features:                                                                           .

A Driver Circuit board for 445-450nm 1W 1.4W 1.6W Laser Diode
Circuit control: 5.5V boost circuit
Diameter: 9X20mm
Reverse Polarity Protection: None
QSP protection: with soft start protection, even if you frequently switch on and off the power supply, it will not cause damage to the laser diodes.
Pin definition: the PCB board shows positive and negative wiring schematic
Recommended working voltage: 3.7V lithium battery (16340,18650,14500 and 18500 powered), or directly using a 5.5V DC power supply.  

Warning:                                                                           .

The default current of the board is 1.3A, the maxiumu current is 1.5A, before soldering your laser diode to this PCB board, make sure the board's current will not be bigger than your laser diode's maximum circuit, otherwise it would burn your laser diode immediatly, Also, heat cooling of laser diode before electric conduction is important, make sure you install the laser diode into the heatsink or holder before connected to the power supply!!!
