Hi,
I have a 5mW green laser pointer but I have broken it while trying a modification. Now I have unmounted it and I dissolded the diode from the circuit board. The diode has 3 pins, is there a way to check if the fault is in the circuit board and the diode is still working?
I have looked for schematics with google and I found 3 circuit layouts: http://www.walshcomptech.com/repairfaq/sam/laserdps.htm#dpsglp1
here you are the schematics:
The question is: if I have understood correctly, according to the schematics the laser diode has 2 pins only, and mine has 3... why? how should I coonect it?
Thanks
