Feature

500mW-1W 445nm/447nm/450nm Blu-ray Drive Circuit Board
a power driver for laser diode/module
Keep it in dry environment away from water or moisture
Please weld the two points when using it,then the product would output current and voltage normally(as the photo showing)

Description

Features:
Circuit control: step-down circuit, constant current output
Dimensions: 15x20mm (W * L)
Power Supply: 5-8V
Output Current: 2.5A constant current
Reverse polarity protection: unique design of reverse polarity protection, you don't have to worry about burning up the board by putting battery reversely
QSP protection: protection with soft start, you don't have to worry about damaging the laser diode even if you switch on and off more than frequently.
Pin definition: the pad especially designed for 445nm drive board, you just need to solder pins according to the pin triangle order, this is not like other boards, for which you have to cut off one pin, or staggered welding!
Polarity Definition: module housing is positive "+", the end pad is negative "-", it is suggested to use two 3.7V lithium battery (16340,18650,14500 or 18500 power supply), or you can used 5.5V DC power supply directly
