Three-wire input, the red line is positive, black line is negative, TTL signal yellow line is positive.
If no signals,the yellow line connect + pole;If it does have signal,yellow line connect positive signals.

Features:
This 980nm laser module with driver built-in is an industrial electronic component and used for Industrial testament, Lab.
This is IR laser which will invisible for human eye,but only for night vision camera or our IR detection Card.Please be aware of it before buying.

The laser module is and precise and sensitive optical instrument. Before carrying on some laser DIY activities, please read about the technical information first and protect your eyes before laser ray. Be sure the operator has experience in optics DIY or testing.
This laser module cannot work for a long time without addtional cooling heatsink, otherwise the laser diode's life would be much shortened or get burnt.
If you need the heatsink to prolong the working time of module,please check the links below
