This is the first time i have tried in post pic's so if they don't show i am working on it  ;)

I have a 10mW 635nm module from AixiZ that i would like to put in a leadlight but i don't know would to use the module as positive or negative input  :-/ so can some one help me?

To find out if it is case negative or positive, put your multimeter on the continuity setting, and put one probe on the positive diode pin, and one on the case of the aixiz module. If the multimeter beeps, then it is case positive. Do the same with the negative pin, and if the multimeter beeps, then the module is case negative. If they don't beep either time, it is case neutral, and you can chooose how you set it.

If you don't have a continuity setting on your multimeter, then disregard what i said

The one I have is case positive.

However, it is easy enough to check. Just power it one way. If it doesn't light up, it is the other way. ;)

Peace,
dave
