درایور لیزر 1 تا 3 وات

laser diode drivers are used to precisely control a laser diode’s optical output while protecting the laser diode from over current conditions. Multiple levels of laser diode protection are included in the design to protect against overcurrent conditions. Features include adjustable current limits, redundant hardware current limits, voltage limit (some models), slow start circuitry, output shorting relays and transient protection.

Circuit control: 5V buck circuit,

constant current output

power supply to ensure stable output: 5.8-12V

Dimensions: 10.2 * 22mm (W * L)

Reverse polarity protection: Unique reverse polarity protection design, you need not worry about the discharge battery will burn board.

Pin definition: 445nm driver board designed specifically for the pad, you simply press the pin welded to the triangular arrangement, not like other boards, like, to cut off a pin, or staggered welding!

Polarity definition: module enclosure is positive, the end of the pad is negative,

Recommend using two 3.7V lithium battery (16340,18650,14500 and 18500 powered), or directly using
