5V-8V Power Supply Driver Board for 445nm 447nm 450nm 500mw-1000mw Blue Laser Diode Module Step-Down Circuit Board

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 Details: This is a power driver for laser diode/module! Widely industrial and LAB use! 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) Package: 1 x 500mW-1W 445nm/447nm/450nm Blu-ray Drive Circuit Board
