Description

Details

Design features:

Circuit control: external MOS, constant current output

Power adjustment: Remove1206 resistor to reducing the output current

Dimensions: 10 * 20mm (W * L)

Reverse polarity protection: Unique reverse polarity protection design, using high-current MOS do reverse, very ordinary transistor

Pin definition: 300~500mW 638nm 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!

Recommend using two 3.7V lithium battery (16340,18650,14500 and 18500 powered), or directly using the 5V DC power supply. 

 

IMPORTANT NOTE: If you are driving a 300mW 638nm diode, simply remove the resistor R030, if it is driven to 500mW, simply remove the top two resistors R100.
