Circuit control：MOS outside built,constant current output
Ouput power adjustable: Remove the resistor 1206 on board then will reduce the current
Reverse protect ：Reverse protect avoid diode burnt to dead even you put battery in opposite direction
Note: If you use it on 638nm 300mW red diodes ,Just take off the resistor R030.
If you drive 500mW red laer diodes ,.Just take off the two R100 resistors
Pin connection：It is suitable for 300-500mW 638nm diodes pin connection，You just sloder in triangle.
Don’t cut one pin or cross soldering!
This driver can be also be for 808nm,660nm laser diodes ,but you should make lead wires then solder
Suggest powerby 3.7V lithium battery （16340，18650，14500 or 18500），or 5VDC power supply
