Hi, I have 4 x 10mw 3.2vdc laser module and I have an AC adapter with a DC3.2V 500mA output.

I bought these last year and can't remember the research I put in, I think my plan was to put them in parallel but now I think I may need resistors?

Please could someone guide me, maybe even link to a tutorial so I can learn it all.

cheers.

They have to be wire in parallel.
And you don't need a resistor. eventually a fuse..

hi, yeh its this one

before I asked, I was reading things about laser diodes, i think this is different being a laser module and I'm thinking it must already have a resistor. I think all I need to know is if it just needs to be wire in parallel now, I assume it can and it's a relatively easy thing to do.

yes, those laser modules have a laser diode and a driver circuit built into the casing
so they are all go for putting across the 3.2V supply

All positives wired with positive, all negatives wired with negative.
On the pictures, it looks ok.
