FS: 100mW rated 650mW laser module + extra diode

6358 is a dual op amp. L7 is likely a 3904 transistor.

It looks like the board has been modified. These boards can be pushed by swapping out a coupel of components, but the transistors usually get over-driven.

Looks like there's a zener shunt there lm431 which is probably programmed to control the voltage, and a cap in parallel to the diode and I'm not sure what 6358 is but i assume it is an op amp. Not sure what the other parts are besides the resistors.

The black component beside the 6359 op9 is labeled L7 and the other black piece on the flp side is labeled J3Y and I have absolutely no idea what these are or what they do.

Not modified by me =) Anyway, does the drive circuit look good to you?

he needs to work on his soldering skills, that's way too hot. burnt pcb = bad especially with smd resistors. they cook and die.

Daedal - you unfixed my fix on his pics ! hehehehe

Ooops... :-?

I finished my post and found the post up there... lol

Sorry, there's not enough detail in the pics to determine that. It looks like a fairly "standard" driver.
