Description

Design features:
Circuit control: 5.5V boost circuit, constant current output, to ensure that the 3-5.5V power supply through the laser output stability
Dimensions: 10.2*20mm (width * length)
Reverse protection: unique anti – protection design, You don't have worry burning it to be dead 
Fast start protection: with a soft start protection, even if you do not have to worry about switching power supply will not worry about damage to laser diode
Pin definition: designed at 405nm drive pad plate design, you only need according to the foot a triangular arrangement of natural welding can be, not like other board to cut off a foot, or staggered welding!
Polar definition: the module shell is positive, at the end of the pad is negative, please refer to the link of welding
Recommended for use with 3.7V lithium battery (163401865014500 and 18500), or directly using 5.5V DC power supply.
